[+NAME?package - source and binary package control]
[+DESCRIPTION?The \bpackage\b command controls source and binary
    packages. It is a \bsh\b(1) script coded for maximal portability. All
    package files are in the \b$PACKAGEROOT\b directory tree.
    \b$PACKAGEROOT\b must at minumum contain a \bbin/package\b command or a
    \blib/package\b directory. Binary package files are in the
    \b$INSTALLROOT\b (\b$PACKAGEROOT/arch/\b\ahosttype\a) tree, where
    \ahosttpe\a=`\bpackage\b`. All \aactions\a but \bhost\b and \buse\b
    require the current directory to be under \b$PACKAGEROOT\b. See
    \bDETAILS\b for more information.]
[+?Note that no environment variables need be set by the user;
    \bpackage\b determines the environment based on the current working
    directory. The \buse\b action starts a \bsh\b(1) with the environment
    initialized. \bCC\b, \bCCFLAGS\b, \bHOSTTYPE\b and \bSHELL\b may be set
    by explicit command argument assignments to override the defaults.]
[+?Packages are composed of components. Each component is built and
    installed by an \bast\b \bnmake\b(1) makefile. Each package is also
    described by an \bnmake\b makefile that lists its components and
    provides a content description. The package makefile and component
    makefiles provide all the information required to read, write, build
    and install packages.]
[+?Package recipients only need \bsh\b(1) and \bcc\b(1) to build and
    install source packages, and \bsh\b to install binary packages.
    \bnmake\b and \bksh93\b are required to write new packages. An
    \b$INSTALLROOT/bin/cc\b script may be supplied for some architectures.
    This script supplies a reasonable set of default options for compilers
    that accept multiple dialects or generate multiple object/executable
    formats.]
[+?The command arguments are composed of a sequence of words: zero or
    more \aqualifiers\a, one \aaction\a, and zero or more action-specific
    \aarguments\a, and zero or more \aname=value\a definitions. \apackage\a
    names a particular package. The naming scheme is a \b-\b separated
    hierarchy; the leftmost parts describe ownership, e.g.,
    \bgnu-fileutils\b, \bast-base\b. If no packages are specified then all
    packages are operated on. \boptget\b(3) documentation options are also
    supported. The default with no arguments is \bhost type\b.]
[+?The qualifiers are:]
    {
        [+authorize \aname\a?Remote authorization user name or license
            acceptance phrase.]
        [+debug|environment?Show environment and actions but do not
            execute.]
        [+flat?Collapse \b$INSTALLROOT\b { bin fun include lib } onto
            \b$PACKAGEROOT\b.]
        [+force?Force the action to override saved state.]
        [+never?Run make -N and show other actions.]
        [+only?Only operate on the specified packages.]
        [+password \apassword\a?Remote authorization or license
	    acceptance password.]
        [+quiet?Do not list captured action output.]
        [+show?Run make -n and show other actions.]
        [+verbose?Provide detailed action output.]
        [+DEBUG?Trace the package script actions in detail.]
    }
[+?The actions are:]
    {
        [+admin\b [\ball\b]] [\bdb\b \afile\a]] [\bon\b \apattern\a]][\aaction\a ...]]?Apply
            \aaction\a ... to the hosts listed in \afile\a. If \afile\a is
            omitted then \badmin.db\b is assumed. The caller must have
            \brcp\b(1) and \brsh\b(1) or \bscp\b(1) and \bssh\b(1) access
            to the hosts. Output for \aaction\a is saved per-host in the
            file \aaction\a\b.log/\b\ahost\a. Logs can be viewed by
            \bpackage admin\b [\bon\b \ahost\a]] \bresults\b [\aaction\a]].
            By default only local PACKAGEROOT hosts are selected from
            \afile\a; \ball\b selects all hosts. \bon\b \apattern\a selects
            only hosts matching the \b|\b separated \apattern\a. \afile\a
            contains four types of lines. Blank lines and lines beginning
            with \b#\b are ignored. Lines starting with \aid\a=\avalue\a
            are variable assignments. Set admin_ping to local conventions
            if \"'$admin_ping$'\" fails. If a package list is not specified
            on the command line the \aaction\a applies to all packages; a
            variable assigment \bpackage\b=\"\alist\a\" applies \aaction\a
            to the packages in \alist\a for subsequent hosts in \afile\a.
            The remaining line type is a host description consisting of 6
            tab separated fields. The first 3 are mandatory; the remaining
            3 are updated by the \badmin\b action. \afile\a is saved in
            \afile\a\b.old\b before update. The fields are:]
            {
                [+hosttype?The host type as reported by
                    \"\bpackage\b\".]
                [+[user@]]host?The host name and optionally user name
                    for \brcp\b(1) and \brsh\b(1) access.]
                [+[remote::[[master]]::]]]]PACKAGEROOT?The absolute remote package
                    root directory and optionally the remote protocol (rsh
                    or ssh) if the directory is on a different server than
                    the master package root directory. If
                    \blib/package/admin/'$admin_env$'\b exists under this
                    directory then it is sourced by \bsh\b(1) before
                    \aaction\a is done. If this field begins with \b-\b
                    then the host is ignored. If this field contains \b:\b
                    then \bditto\b(1) is used to sync the remote \bsrc\b
                    directory hierarchy to the local one. If [\amaster\a]]:
		    is specified then the sync is deferred to the \amaster\a
		    host. If \amaster\a is omitted (two :) then the sync is
		    disabled. These directories must exist on the remote side:
		    \blib/package\b, \bsrc/cmd\b, \bsrc/lib\b.]
                [+date?\aYYMMDD\a of the last action.]
                [+time?Elapsed wall time for the last action.]
                [+M T W?The \badmin\b action \bmake\b, \btest\b and
                    \bwrite\b action error counts. A non-numeric value in
                    any of these fields disables the corresponding action.]
	    	[+owner?The owner contact information.]
		[+attributes?\aname=value\a attributes. Should at least contain
		    \bcc\b=\acompiler-version\a.]
            }
	[+clean | clobber?Delete the \barch/\b\aHOSTTYPE\a hierarchy; this
	    deletes all generated files and directories for \aHOSTTYPE\a.
	    The heirarchy can be rebuilt by \bpackage make\b.]
        [+contents\b [ \apackage\a ... ]]?List description and
            components for \apackage\a on the standard output.]
        [+copyright\b [ \apackage\a ... ]]?List the general copyright
            notice(s) for \apackage\a on the standard output. Note that
            individual components in \apackage\a may contain additional or
            replacement notices.]
        [+export\b [ \avariable\a ...]]?List \aname\a=\avalue\a for
            \avariable\a, one per line. If the \bonly\b attribute is
            specified then only the variable values are listed. If no
	    variables are specified then \b'$env$'\b are assumed.]
        [+help\b [ \aaction\a ]]?Display help text on the standard
            error (standard output for \aaction\a).]
        [+host\b [ \aattribute\a ... ]]?List
            architecture/implementation dependent host information on the
            standard output. \btype\b is listed if no attributes are
            specified. Information is listed on a single line in
            \aattribute\a order. The attributes are:]
            {
                [+canon \aname\a?An external host type name to be
                    converted to \bpackage\b syntax.]
                [+cpu?The number of cpus; 1 if the host is not a
                    multiprocessor.]
                [+name?The host name.]
                [+rating?The cpu rating in pseudo mips; the value is
                    useful useful only in comparisons with rating values of
                    other hosts. Other than a vax rating (mercifully) fixed
                    at 1, ratings can vary wildly but consistently from
                    vendor mips ratings. \bcc\b(1) may be required to
                    determine the rating.]
                [+type?The host type, usually in the form
                    \avendor\a.\aarchitecture\a, with an optional trailing
                    -\aversion\a. The main theme is that type names within
                    a family of architectures are named in a similar,
                    predictable style. OS point release information is
                    avoided as much as possible, but vendor resistance to
                    release incompatibilities has for the most part been
                    futile.]
            }
        [+html\b [ \aaction\a ]]?Display html help text on the standard
            error (standard output for \aaction\a).]
        [+install\b [ \aarchitecture\a ... ]] \adirectory\a [ \apackage\a ... ]]?Copy
            the package binary hierarchy to \adirectory\a. If
            \aarchitecture\a is omitted then all architectures are
            installed. If \bflat\b is specified then exactly one
            \aarchitecture\a must be specified; this architecture will be
            installed in \adirectory\a without the \barch/\b\aHOSTTYPE\a
            directory prefixes. Otherwise each architecture will be
            installed in a separate \barch/\b\aHOSTTYPE\a subdirectory of
            \adirectory\a. The \aarchitecture\a \b-\b names the current
            architecture. \adirectory\a must be an existing directory. If
            \apackage\a is omitted then all binary packages are installed.
            This action requires \bnmake\b.]
        [+license\b [ \apackage\a ... ]]?List the source license(s) for
            \apackage\a on the standard output. Note that individual
            components in \apackage\a may contain additional or replacement
            licenses.]
        [+list\b [ \apackage\a ... ]]?List the name, version and
            prerequisites for \apackage\a on the standard output.]
        [+make\b [ \apackage\a ]] [ \aoption\a ... ]] [ \atarget\a ... ]]?Build
	    and install. The default \atarget\a is \binstall\b, which makes
	    and installs \apackage\a. If the standard output is a terminal
	    then the output is also captured in
            \b$INSTALLROOT/lib/package/gen/make.out\b. The build is done in
            the \b$INSTALLROOT\b directory tree viewpathed on top of the
            \b$PACKAGEROOT\b directory tree. If \bflat\b is specified then
            the \b$INSTALLROOT\b { bin fun include lib } directories are
            linked to the same directories in the package root. Only one
            architecture may be \bflat\b. Leaf directory names matching the
            \b|\b-separated shell pattern \b$MAKESKIP\b are ignored. The
            \bview\b action is done before making. \aoption\a operands are
	    passed to the underlying make command.]
        [+read\b [ \apackage\a ... | \aarchive\a ... ]]?Read the named
            package or archive(s). Must be run from the package root
            directory. Archives are searched for in \b.\b and
            \blib/package/tgz\b. Each package archive is read only once.
            The file \blib/package/tgz/\b\apackage\a[.\atype\a]]\b.tim\b
            tracks the read time. See the \bwrite\b action for archive
            naming conventions. Text file archive member are assumed to be
            ASCII or UTF-8 encoded.]
        [+regress?\bdiff\b(1) the current and previous \bpackage test\b
            results.]
        [+release\b [ [\aCC\a]]\aYY-MM-DD\a [ [\acc\a]]\ayy-mm-dd\a ]]]] [ \apackage\a ]]?Display
            recent changes for the date range [\aCC\a]]\aYY-MM-DD\a (up to
        [\acc\a]]\ayy-mm-dd\a.), where \b-\b means lowest (or highest.)
            If no dates are specified then changes for the last 4 months
            are listed. \apackage\a may be a package or component name.]
        [+remove\b [ \apackage\a ]]?Remove files installed for
            \apackage\a.]
        [+results\b [ \bfailed\b ]] [ \bpath\b ]] [ \bold\b ]] [\bmake\b | \btest\b | \bwrite\b ]]?List
            results and interesting messages captured by the most recent
            \bmake\b (default), \btest\b or \bwrite\b action. \bold\b
            specifies the previous results, if any (current and previous
            results are retained.) \b$HOME/.pkgresults\b, if it exists,
            must contain an \begrep\b(1) expression of result lines to be
            ignored. \bfailed\b lists failures only and \bpath\b lists the
            results file path name only.]
        [+setup\b [ beta ]] [ binary ]] [ source ]] [ \aarchitecture\a ... ]] [ \aurl\a ]] [ \apackage\a ... ]]?This
            action initializes the current directory as a package root, runs the
            \bupdate\b action to download new or out of date packages, and runs the
            \bread\b action on those packages. If \bflat\b is specified then the
            \b$INSTALLROOT\b { bin fun include lib } directories are linked to the
            same directories in the package root. Only one architecture may be
            \bflat\b. See the \bupdate\b and \bread\b action descriptions for
            argument details.]
        [+test\b [ \apackage\a ]]?Run the regression tests for
            \apackage\a. If the standard output is a terminal then the
            output is also captured in
            \b$INSTALLROOT/lib/package/gen/test.out\b. In general a package
            must be made before it can be tested. Components tested with
            the \bregress\b(1) command require \bksh93\b. If \bonly\b is
	    also specified then only the listed package components are
	    tested, otherwise the closure of the components is tested.]
        [+update\b [ beta ]] [ binary ]] [ source ]] [\aarchitecture\a ... ]] [ \aurl\a ]] [ \apackage\a ... ]]?Download
            the latest release of the selected and required packages from \aurl\a
            (e.g., \bhttp://www.research.att.com/sw/download\b) into the directory
            \b$PACKAGEROOT/lib/package/tgz\b. \bbeta\b acesses beta packages;
            download these at your own risk. If \aarchitecture\a is omitted then
            only architectures already present in the \btgz\b directory will be
            downloaded. If \aarchitecture\a is \b-\b then all posted architectures
            will be downloaded. If \aurl\a matches \b*.url\b then it is interpreted
            as a file containing shell variable assignments for \burl\b,
            \bauthorize\b and \bpassword\b. If \aurl\a is omitted then the
            definitions for \burl\b, \bauthorize\b and \bpassword\b in
            \b$PACKAGEROOT/lib/package/tgz/default.url\b, if it exists, are used.
            If \b$PACKAGEROOT/lib/package/tgz/default.url\b does not exist then it
            is initialized with the current \burl\b, \bauthorize\b and \bpassword\b
            values and read permission for the current user only. If \apackage\a is
            omitted then only packages already present in the tgz directory will be
            downloaded. If \apackage\a is \b-\b then all posted packages will be
            downloaded. If \bsource\b and \bbinary\b are omitted then both source
            and binary packages will be downloaded. If \bonly\b is specified then
            only the named packages are updated; otherwise the closure of required
            packages is updated. This action requires \bwget\b(1), \blynx\b(1),
            \bcurl\b(1) or a shell that supports io to
	    \b/dev/tcp/\b\ahost\a/\aport\a.]
        [+use\b [ \auid\a | \apackage\a | . [ 32 | 64 ]] | 32 | 64 | - ]] [ command ...]]?Run
            \acommand\a, or an interactive shell if \acommand\a is omitted,
            with the environment initialized for using the package (can you
            say \ashared\a \alibrary\a or \adll\a without cussing?) If
            \auid\a or \apackage\a or \a.\a is specified then it is used
	    to determine a \b$PACKAGEROOT\b, possibly different from
	    the current directory. For example, to try out bozo`s package:
            \bpackage use bozo\b. The \buse\b action may be run from any
            directory. If the file \b$INSTALLROOT/lib/package/profile\b is
            readable then it is sourced to initialize the environment. 32 or 64
	    implies \b$PACKAGEROOT\b of . and specifies the target architecture
	    word size (which may be silently ignored.)]
        [+verify\b [ \apackage\a ]]?Verify installed binary files
            against the checksum files in
            \b$INSTALLROOT/lib/\b\apackage\a\b/gen/*.sum\b. The checksum
            files contain mode, user and group information. If the checksum
            matches for a given file then the mode, user and group are
            changed as necessary to match the checksum entry. A warning is
            printed on the standard error for each mismatch. Requires the
            \bast\b package \bcksum\b(1) command.]

            hierarchy. If \bflat\b is specified then the \b$INSTALLROOT\b {

            directories in the package root. Only one architecture may be
            \bflat\b. The \bmake\b action implicitly calls this action.]
        [+write\b [\aformat\a]] \atype\a ... [ \apackage\a ...]]?Write
            a package archive for \apackage\a. All work is done in the
            \b$PACKAGEROOT/lib/package\b directory. \aformat\a-specific
            files are placed in the \aformat\a subdirectory. A
            \apackage\a[.\atype\a]]\b.tim\b file in this directory tracks
            the write time and prevents a package from being read in the
            same root it was written. If more than one file is generated
            for a particular \aformat\a then those files are placed in the
            \aformat\a/\apackage\a subdirectory. File names in the
            \aformat\a subdirectory will contain the package name, a
            \ayyyy-mm-dd\a date, and for binary packages, \aHOSTTYPE\a. If
            \apackage\a is omitted then an ordered list of previously
            written packages is generated. If \bonly\b is specified then
            only the named packages will be written; otherwise prerequisite
            packages are written first. Package components must be listed
            in \apackage\a\b.pkg\b. \aformat\a may be one of:]

                [+lcl?Generate a package archive suitable for
                    restoration into the local source tree (i.e., the
                    source is not annotated for licencing.)]
                [+pkg?Generate a \bpkgmk\b(1) package suitable for

		    \btst\b subdirectory. Version state files are not updated.]
            }
        [+?\btype\b specifies the package type which must be one of
            \bsource\b, \bbinary\b or \bruntime\b. A source package
            contains the source needed to build the corresponding binary
            package. A binary package includes the libraries and headers
            needed for compiling and linking against the public interfaces.
            A runtime package contains the commands and required dynamic
            libraries.]
        [+?A package may be either a \bbase\b or \bdelta\b. A base
            package contains a complete copy of all components. A delta
            package contains only changes from a previous base package.
            Delta recipients must have the \bast\b \bpax\b(1) command (in
            the \bast-base\b package.) If neither \bbase\b nor \bdelta\b is
            specified, then the current base is overwritten if there are no
            deltas referring to the current base. Only the \btgz\b and
            \blcl\b formats support \bdelta\b. If \bbase\b is specified
            then a new base and two delta archives are generated: one delta
            to generate the new base from the old, and one delta to
            generate the old base from the new; the old base is then
            removed. If \bdelta\b is specified then a new delta referring
            to the current base is written.]
        [+?\apackage\a\b.pkg\b may reference other packages. By default
            a pointer to those packages is written. The recipient \bpackage
            read\b will then check that all required packages have been
            downloaded. If \bclosure\b is specified then the components for
            all package references are included in the generated package.
            This may be useful for \blcl\b and versioning.]
        [+?All formats but \blcl\b annotate each \bsource\b file (not
            already annotated) with a license comment as it is written to
            the package archive using \bproto\b(1).]
    }
[+DETAILS?The package directory hierarchy is rooted at
    \b$PACKAGEROOT\b. All source and binaries reside under this tree. A two
    level viewpath is used to separate source and binaries. The top view is
    architecture specific, the bottom view is shared source. All building
    is done in the architecture specific view; no source view files are
    intentionally changed. This means that many different binary
    architectures can be made from a single copy of the source.]
[+?Independent \b$PACKAGEROOT\b hierarchies can be combined by
    appending \b$INSTALLROOT:$PACKAGEROOT\b pairs to \bVPATH\b. The
    \bVPATH\b viewing order is from left to right. Each \b$PACKAGEROOT\b
    must have a \b$PACKAGEROOT/lib/package\b directory.]
[+?Each package contains one or more components. Component source for
    the \afoo\a command is in \b$PACKAGEROOT/src/cmd/\b\afoo\a, and source
    for the \abar\a library is in \b$PACKAGEROOT/src/lib/lib\b\abar\a. This
    naming is for convenience only; the underlying makefiles handle
    inter-component build order. The \bINIT\b component, which contains
    generic package support files, is always made first, then the
    components named \bINIT\b*, then the component order determined by the
    closure of component makefile dependencies.]
[+?\b$PACKAGEROOT/lib/package\b contains package specific files. The
    package naming convention is \agroup\a[-\apart\a]]; e.g., \bast-base\b,
    \bgnu-fileutils\b. The *\b.pkg\b files are ast \bnmake\b(1) makefiles
    that contain the package name, package components, references to other
    packages, and a short package description. *\b.pkg\b files are used by
    \bpackage write\b to generate new source and binary packages.]
[+?\b$PACKAGEROOT/lib/package/\b\agroup\a\b.lic\b files contain license
    information that is used by the \bast\b \bproto\b(1) and \bnmake\b(1)
    commands to generate source and binary license strings. \agroup\a is
    determined by the first \b:PACKAGE:\b operator name listed in the
    component \bnmake\b makefile. \agroup\a\b.lic\b files are part of the
    licensing documentation. Each component may have its own \bLICENSE\b file
    that overrides the \agroup\a\b.lic\b file. The full text of the licenses
    are in the \b$PACKAGEROOT/lib/package/LICENSES\b and
    \b$INSTALLROOT/lib/package/LICENSES\b directories.]
[+?A few files are generated in \b$PACKAGEROOT/lib/package/gen\b and
    \b$INSTALLROOT/lib/package/gen\b. \apackage\a\b.ver\b contains one line
    consisting of \apackage version release\a \b1\b for the most recent
    instance of \apackage\a read into \b$PACKAGEROOT\b, where \apackage\a
    is the package name, \aversion\a is the \aYYYY-MM-DD\a base version,
    and \arelease\a is \aversion\a for the base release or \aYYYY-MM-DD\a
    for delta releases. \apackage\a\b.req\b contains *\b.ver\b entries for
    the packages required by \apackage\a, except that the fourth field is
    \b0\b instead of \b1\b. All packages except \bINIT\b require the
    \bINIT\b package. A simple sort of \apackage\a\b.pkg\b and *\b.ver\b
    determines if the required package have been read in. Finally,
    \apackage\a\b.README\b and \apackage\a\a.html\b contain the README text
    for \apackage\a and all its components. Included are all changes added
    to the component \bRELEASE\b, \bCHANGES\b or \bChangeLog\b files dated
    since the two most recent base releases. Component \bRELEASE\b files
    contain tag lines of the form [\aYY\a]]\aYY-MM-DD\a [ \atext\a ]] (or
    \bdate\b(1) format dates) followed by README text, in reverse
    chronological order (newer entries at the top of the file.) \bpackage
    release\b lists this information, and \bpackage contents ...\b lists
    the descriptions and components.]
[+?\b$HOSTYPE\b names the current binary architecture and is determined
    by the output of \bpackage\b (no arguments.) The \b$HOSTTYPE\b naming
    scheme is used to separate incompatible executable and object formats.
    All architecture specific binaries are placed under \b$INSTALLROOT\b
    (\b$PACKAGEROOT/arch/$HOSTTYPE\b.) There are a few places that match
    against \b$HOSTTYPE\b when making binaries; these are limited to
    makefile compiler workarounds, e.g., if \b$HOSTTYPE\b matches \bhp.*\b
    then turn off the optimizer for these objects. All other architecture
    dependent logic is handled either by the \bast\b \biffe\b(1) command or
    by component specific configure scripts. Explicit \b$HOSTYPE\b
    values matching *,*cc*[,-*,...]] optionally set the default \bCC\b and
    \bCCFLAGS\b. This is handy for build farms that support different
    compilers on the same architecture.]
[+?Each component contains an \bast\b \bnmake\b(1) makefile (either
    \bNmakefile\b or \bMakefile\b) and a \bMAM\b (make abstract machine)
    file (\bMamfile\b.) A Mamfile contains a portable makefile description
    that is used by \bmamake\b(1) to simulate \bnmake\b. Currently there is
    no support for old-make/gnu-make makefiles; if the binaries are just
    being built then \bmamake\b will suffice; if source or makefile
    modifications are anticipated then \bnmake\b (in the \bast-base\b
    package) should be used. Mamfiles are automatically generated by
    \bpackage write\b.]
[+?Most component C source is prototyped. If \b$CC\b (default value
    \bcc\b) is not a prototyping C compiler then \bpackage make\b runs
    \bproto\b(1) on portions of the \b$PACKAGEROOT/src\b tree and places
    the converted output files in the \b$PACKAGEROOT/proto/src\b tree.
    Converted files are then viewpathed over the original source.
    \bproto\b(1) converts an ANSI C subset to code that is compatible with
    K&R, ANSI, and C++ dialects.]
[+?All scripts and commands under \b$PACKAGEROOT\b use \b$PATH\b
    relative pathnames (via the \bast\b \bpathpath\b(3) function); there
    are no imbedded absolute pathnames. This means that binaries generated
    under \b$PACKAGEROOT\b may be copied to a different root; users need
    only change their \b$PATH\b variable to reference the new installation
    root \bbin\b directory. \bpackage install\b installs binary packages in
    a new \b$INSTALLROOT\b.]

${bH}Package Hierarchy Details${eH}
${bP}
The package directory hierarchy is rooted at ${bB}\$PACKAGEROOT${eB}. All source and
binaries reside under this tree. A two level viewpath is used to separate
source and binaries. The top view is architecture specific, the bottom view
is shared source. All building is done in the architecture specific view;
no source view files are intentionally changed. This means that many
different binary architectures can be made from a single copy of the source.
${bP}
Each package contains one or more components. Component source for the ${bI}FOO${eI}
command is in ${bB}\$PACKAGEROOT/src/cmd/${eB}${bI}FOO${eI}, and source for the ${bI}BAR${eI} library is
in ${bB}\$PACKAGEROOT/src/lib/lib${eB}${bI}BAR${eI}. This naming is for convenience only; the
underlying makefiles handle inter-component build order. The ${bB}INIT${eB} component,
which contains generic package support files, is always made first, then the
components named ${bB}INIT${eB}*, then the order determined by the closure of component
makefile dependencies.
${bP}
${bB}\$PACKAGEROOT/lib/package${eB} contains package specific files. The package naming
convention is ${bI}GROUP${eI}[${bI}-PART${eI}]; e.g., ${bB}ast-base${eB}, ${bB}gnu-fileutils${eB}. The *${bB}.pkg${eB} files
are ${bB}ast${eB} ${Mnmake} makefiles that contain the package name, package components,
references to other packages, and a short package description. *${bB}.pkg${eB} files
are used by ${bF}package write${eF} to generate new source and binary packages.
${bP}
${bB}\$PACKAGEROOT/lib/package/${eB}${bI}GROUP${eI}${bB}.lic${eB} files contain license information that
is used by the ${bB}ast${eB} ${Mproto} and ${Mnmake} commands to generate source and
binary license strings. ${bI}GROUP${eI} is determined by the first ${bB}:PACKAGE:${eB} operator
name listed in the component ${bB}nmake${eB} makefile. ${bI}GROUP${eI}${bB}.lic${eB} files are part of the
licensing documentation.  Each component may have its own ${bB}LICENSE${eB} file that
overrides the ${bI}GROUP${eI}${bB}.lic${eB} file.  The full text of the licenses are in the

A few files are generated in ${bB}\$PACKAGEROOT/lib/package/gen${eB} and
${bB}\$INSTALLROOT/lib/package/gen${eB}. ${bI}PACKAGE${eI}${bB}.ver${eB} contains one line consisting of${bX}
	${bI}PACKAGE VERSION RELEASE${eI} 1${eX}
for the most recent instance of ${bI}PACKAGE${eI} read into ${bB}\$PACKAGEROOT${eB}, where
${bI}PACKAGE${eI} is the package name, ${bI}VERSION${eI} is the ${bI}YYYY-MM-DD${eI} base version,
and ${bI}RELEASE${eI} is ${bI}VERSION${eI} for the base release or ${bI}YYYY-MM-DD${eI} for delta releases.
${bI}PACKAGE${eI}${bB}.req${eB} contains *${bB}.ver${eB} entries for the packages required by
${bI}PACKAGE${eI}, except that the fourth field is 0 instead of 1. All packages
except ${bB}INIT${eB} and ${Mratz} require the ${bB}INIT${eB} package. A simple sort of ${bI}PACKAGE${eI}${bB}.pkg${eB}
and *${bB}.ver${eB} determines if the required package have been read in. Finally,
${bI}PACKAGE${eI}${bB}.README${eB} contains the ${bB}README${eB} text for ${bI}PACKAGE${eI} and all its
components. Included are all changes added to the component ${bB}RELEASE${eB},
${bB}CHANGES${eB} or ${bB}ChangeLog${eB} files dated since the two most recent base
releases. Component ${bB}RELEASE${eB} files contain tag lines of the form
[${bI}CC${eI}]${bI}YY-MM-DD${eI} [ ${bI}TEXT${eI} ] (or ${Mdate} format dates) followed by README
text, in reverse chronological order (newer entries at the top of the
file.) ${bF}package release${eF} generates this information, and
${bF}package contents ...${eF} lists the descriptions and components.
${bP}
${bB}\$HOSTYPE${eB} names the current binary architecture and is determined by the
output of ${bF}package${eF} (no arguments.) The ${bB}\$HOSTTYPE${eB} naming scheme is used
to separate incompatible executable and object formats. All architecture
specific binaries are placed under ${bB}\$INSTALLROOT${eB} (${bB}\$PACKAGEROOT/arch/\$HOSTTYPE${eB}.)
There are a few places that match against ${bB}\$HOSTTYPE${eB} when making binaries; these
are limited to makefile compiler workarounds, e.g., if ${bB}\$HOSTTYPE${eB} matches
'hp.*' then turn off the optimizer for these objects. All other architecture
dependent logic is handled either by ${bB}\$INSTALLROOT/bin/iffe${eB} or by component
specific configure scripts. Explicit ${bB}\$HOSTYPE${eB} values matching *,*cc*[,-*,...]
optionally set the default ${bB}CC${eB} and ${bB}CCFLAGS${eB}. This is handy for build
farms that support different compilers on the same architecture.
${bP}
Each component contains an ${bB}ast${eB} ${Mnmake} makefile (either ${bB}Nmakefile${eB} or ${bB}Makefile${eB})
and a ${bI}MAM${eI} (make abstract machine) file (${bB}Mamfile${eB}.) A Mamfile contains a portable
makefile description that is used by ${bB}\$INSTALLROOT/bin/mamake${eB} to simulate
${bB}nmake${eB}. Currently there is no support for old-make/gnu-make makefiles; if
the binaries are just being built then ${bB}mamake${eB} will suffice; if source or
makefile modifications are anticipated then ${bB}nmake${eB} (from the ${bB}ast-open${eB} or
${bB}ast-base${eB} package) should be used. Mamfiles are automatically generated by
${bF}package write${eF}.
${bP}
Most component C source is prototyped. If ${bB}\$CC${eB} (default value ${bB}cc${eB}) is not a
prototyping C compiler then ${bF}package make${eF} runs ${Mproto} on portions of the
${bB}\$PACKAGEROOT/src${eB} tree and places the converted output files in the
${bB}\$PACKAGEROOT/proto/src${eB} tree. Converted files are then viewpathed over the
original source. The ${bB}ast${eB} ${Mproto} command converts an ANSI C subset to code
that is compatible with K&R, ANSI, and C++ dialects.
${bP}
All scripts and commands under ${bB}\$PACKAGEROOT${eB} use ${bB}\$PATH${eB} relative pathnames;
there are no imbedded absolute pathnames. This means that binaries generated
under ${bB}\$PACKAGEROOT${eB} may be copied to a different root; users need only change
their ${bB}\$PATH${eB} variable to reference the new instalation root bin directory.
${bF}package install${eF} installs binary packages in a new ${bB}\$INSTALLROOT${eB}.

		*)	echo "Usage: $command [ qualifier ... ] [ action ] [ arg ... ] [ n=v ... ]

   The $command command controls source and binary packages. It must be run
   within the package root directory tree. See \"$command help intro\" for
   details. In the following, PACKAGE names either a package or a component
   within a package; if omitted, all packages are operated on. The default
   action is \"host type\".

   qualifier:
	authorize NAME Remote authorization name or license acceptance phrase.
	debug|environment Show environment and actions; do not execute.
	flat    Collapse \$INSTALLROOT { bin fun include lib } onto \$PACKAGEROOT.
	force	Force the action to override saved state.
	never	Run make -N; otherwise show other actions.
	only	Only operate on the specified packages.
	password PASSWORD Remote authorization or license acceptance password.
	quiet	Do not list captured make and test action output.
	show	Run make -n; otherwise show other actions.
	DEBUG	Trace the package script actions in detail for debugging.
   action:
	admin [ all ] [ db FILE ] [ on PATTERN ] [ action ... ]
		Apply ACTION ... to the hosts listed in FILE. If FILE is
		omitted then "admin.db" is assumed. The caller must have rcp(1)
		and rsh(1) or scp(1) and ssh(1) access to the hosts. Output
		for the action is saved per-host in ACTION.log/HOST. Logs
		can be viewed by \"package admin [on HOST] results [ACTION]\".
		By default only local PACKAGEROOT hosts are selected from FILE;
		\"all\" selects all hosts. \"on PATTERN\" selects only
		hosts matching the | separated PATTERN. FILE contains four
		types of lines. Blank lines and lines beginning with # are
		ignored. Lines starting with id=value are variable assignments.
		Set admin_ping to local conventions if \"$admin_ping\" fails.
		If a package list is not specified on the command line the
		action applies to all packages; a variable assigment
		package=list applies action to the packages in list for
		subsequent hosts in FILE. The remaining line type is a host
		description consisting of 6 tab separated fields. The first 3
		are mandatory; the remaining 3 are updated by the admin action:
		   hosttype
			   The host type as reported by package.
		   [user@]host
			   The host name and optionally user name for rcp(1)
			   and rsh(1) access.
		   [remote:[[master]:]]PACKAGEROOT
			   The absolute remote package root directory and
			   optionally the remote prorocol (rsh or ssh) if
			   the directory is on a different server than the
			   master package root directory. If
			   lib/package/admin/$admin_env exists under
			   this directory then it is sourced by sh(1)
			   before ACTION is done. If this field begins with -
			   then the host is ignored. If this field contains
			   : then ditto(1) is used to sync the remote src
			   directory hierarchy to the local one. If [master]:
			   is specified then the sync is deferred to the
			   master host. If master is omitted (two :) then
			   the sync is disabled. These directories must exist
			   on the remote side: lib/package, src/cmd, src/lib.
		   date    YYMMDD of the last action.
		   date    Elapsed wall time of the last action.
		   M T W   The admin action make, test and write action error
			   counts. A non-numeric value in any of these fields
			   disables the corresponding action.
	    	   owner   The owner contact information.
		   attributes
		           NAME=VALUE attributes. Should at least contain
			   cc=compiler-version.
	clean | clobber
	    Delete the arch/HOSTTYPE hierarchy; this deletes all generated
	    files and directories for HOSTTYPE. The heirarchy can be rebuilt
	    by package make.]
	contents [ package ... ]
		List description and components for PACKAGE on the standard
		output.
	copyright [ package ... ]
		List the general copyright notice(s) for PACKAGE on the
		standard output. Note that individual components in PACKAGE
		may contain additional or replacement notices.
	export [ VARIABLE ... ]
		List NAME=VALUE for each VARIABLE, one per line. If the
		\"only\" attribute is specified then only the variable
		values are listed. If no variables are specified then
		$env are assumed.
	help [ ACTION ]
		Display help text on the standard error [ standard output
		for ACTION ].
	host [ canon cpu name rating type ... ]
		List architecture/implementation dependent host information
		on the standard output. type is listed if no attributes are
		specified. Information is listed on a single line in attributes
		order. The attributes are:
		   canon   The next argument is a host type name to be
			   converted to package syntax.
		   cpu     The number of cpus; 1 if the host is not a
			   multiprocessor.
		   name    The host name.
		   rating  The cpu rating in pseudo mips; the value is useful
			   useful only in comparisons with rating values of
			   other hosts. Other than a vax rating fixed at 1,
			   ratings can vary wildly but consistently from
			   vendor mips ratings. cc(1) may be required to
			   determine the rating.
	           type    The host type, usually of the form
			   vendor.architecture, with an optional trailing
			   -version. The main theme is that type names within
			   a family of architectures are named in a similar,
			   predictable style. Os point release information is
			   avoided as much as possible, but vendor resistance
			   to release incompatibilities has for the most part
			   been futile.
	html [ ACTION ]
		Display html help text on the standard error [ standard output
		for ACTION ].
	install [ ARCHITECTURE ... ] DIR [ PACKAGE ... ]
		Copy the package binary hierarchy to DIR. If ARCHITECTURE is
		omitted then all architectures are installed. If the \"flat\"
		attribute is specified then exactly one ARCHITECTURE must be
		specified; this architecture will be installed in DIR without
		the \"arch/HOSTTYPE\" directory prefixes. Otherwise each
		architecture will be installed in a separate \"arch/HOSTTYPE\"
		subdirectory of DIR. The ARCHITECTURE - names the current
		architecture. DIR must be an existing directory. If PACKAGE
		is omitted then all binary packages are installed. This action
		requires nmake.
	license [ package ... ]
		List the source license(s) for PACKAGE on the standard output.
		Note that individual components in PACKAGE may contain
		additional or replacement licenses.
	list [ PACKAGE ... ]
		List the name, version and prerequisites for PACKAGE on the
		standard output.
	make [ PACKAGE ] [ OPTION ... ] [ TARGET ... ]
		Build and install. The default TARGET is install, which
		makes and installs all packages. If the standard output
		is a terminal then the output is also captured in
		\$INSTALLROOT/lib/package/gen/make.out. The build is done
		in the \$INSTALLROOT directory tree viewpathed on top of
		the \$PACKAGEROOT directory tree. If \"flat\" is specified then
		the \$INSTALLROOT { bin fun include lib } directories are
		linked to the same directories in the package root. Only
		one architecture may be flat. Leaf directory names matching
		the |-separated shell pattern \$MAKESKIP are ignored. The
		view action is done before making. OPTION operands are
		passed to the underlying make command.
	read [ package ... | archive ... ]
		Read the named package archive(s). Must be run from the
		package root directory. Archives are searched for in .
		and lib/package/tgz. Each package is read only once. The
		file lib/package/tgz/package[.type].tim tracks the read time.
		See the write action for archive naming conventions. Text
		file archive member are assumed to be ASCII or UTF-8 encoded.
	regress diff(1) the current and previous package test results.
	release [ [CC]YY-MM-DD [ [cc]yy-mm-dd ] ] [ package ]
		Display recent changes since [CC]YY-MM-DD (up to [cc]yy-mm-dd),
		where - means lowest (or highest.) If no dates are specified
		then changes for the last 4 months are listed. PACKAGE may
		be a package or component name.
	remove PACKAGE
		Remove files installed for PACKAGE.
	results [ path ] [ old ] [ make | test ]
		List results and interesting messages captured by the most
		recent make (default), test or write action. old specifies the
		previous results, if any (current and previous results are
		retained.) $HOME/.pkgresults, if it exists, must contain an
		egrep(1) expression of result lines to be ignored. failed lists
		failures only and path lists the results file path only.
	setup [ beta ] [ binary ] [ source ] [ ARCHITECTURE ... ] [ URL ] [ PACKAGE ... ]
		The action initializes the current directory as a package root,
		runs the update action to download new or out of date packages,
		and runs the read action on those packages. If \"flat\" is
		specified then the \$INSTALLROOT { bin fun include lib }
		directories are linked to the same directories in the package
		root. Only one architecture may be flat. See the update and
		read actions for argument details.
	test [ PACKAGE ]
		Run the regression tests for PACKAGE. If the standard output
		is a terminal then the output is also captured in
		\$INSTALLROOT/lib/package/gen/test.out. In general a package
		must be made before it can be tested. Components tested with
		the \bregress\b(1) command require \bksh93\b. If only is
		also specified then only the listed package components are
		tested, otherwise the closure of the components is tested.
	update [ beta ] [ binary ] [ source ] [ ARCHITECTURE ... ] [ URL ] [ PACKAGE ... ]
		Download the latest release of the selected and required
		packages from URL (e.g.,
		http://www.research.att.com/sw/download) into the directory
		\$PACKAGEROOT/lib/package/tgz. beta acesses beta packages;
		download these at your own risk. If ARCHITECTURE is omitted
		then only architectures already present in the tgz directory
		will be downloaded. If ARCHITECTURE is - then all posted
		architectures will be downloaded. If URL matches *.url then
		it is interpreted as a file containing shell variable
		assignments for url, authorize and password. If URL is
		omitted then the definitions for url, authorize and password
		in \$PACKAGEROOT/lib/package/tgz/$default_url, if it exists,
		are used. If \$PACKAGEROOT/lib/package/tgz/$default_url does
		not exist then it is initialized with the current url,
		authorize and password values and read permission for the
		current user only. If PACKAGE is omitted then only
		packages already present in the tgz directory will be
		downloaded. If PACKAGE is - then all posted packages will be
		downloaded. If source and binary are omitted then both source
		and binary packages will be downloaded. If \bonly\b is
		specified then only the named packages are updated; otherwise
		the closure of required packages is updated. This action
		requires wget(1), lynx(1), curl(1) or a shell that supports
		io to /dev/tcp/HOST/PORT.
   	use [ uid | PACKAGE | . [ 32 | 64 ] | 32 | 64 | - ] [ COMMAND ... ]
   		Run COMMAND or an interactive shell if COMMAND is omitted, with
		the environment initialized for using the package (can you say
		shared library without cussing?) If uid or PACKAGE or . is
		specified then it is used to determine a \$PACKAGEROOT,
		possibly different from the current directory. For example, to
		try out bozo's package: \"package use bozo\". In this case the
		command may be run from any directory. If the file
		\$INSTALLROOT/lib/package/profile is readable then it is
		sourced to initialize the environment. 32 or 64 implies
		\$PACKAGEROOT of . and specifies the target architecture word
		size (which may be silently ignored.)
	verify [ PACKAGE ]
		Verify installed binary files against the checksum files in
		\$INSTALLROOT/lib/package/gen/*.sum. The checksum files contain
		mode, user and group information. If the checksum matches
		for a given file then the mode, user and group are changed
		as necessary to match the checksum entry. A warning is printed
		on the standard error for each mismatch. Requires the ast
		package cksum(1) command.
	view
		Initialize the architecture specific viewpath hierarchy. The
		make action implicitly calls this action. If \"flat\" is specified
		then the \$INSTALLROOT { bin fun include lib } directories are
		linked to the same directories in the package root. Only one
		architecture may be flat.
	write [closure] [cyg|exp|lcl|pkg|rpm|tgz|tst] [base|delta]
			[binary|runtime|source] PACKAGE
		Write a package archive for PACKAGE. All work is done in the
		\$PACKAGEROOT/lib/package directory. FORMAT-specific files
		are placed in the FORMAT subdirectory. A PACKAGE[.TYPE].tim
		file in this directory tracksthe write time and prevents a
		package from being read in the same root it was written. If
		more than one file is generated for a particular FORMAT then
		those files are placed in the FORMAT/PACKAGE subdirectory.
		File names in the FORMAT subdirectory will contain the package
		name, a YYYY-MM-DD date, and for binary packages, HOSTTYPE.
		If PACKAGE is omitted then an ordered list of previously
		written packages is generated. If \"only\" is specified then
		only the named packages will be written; otherwise
		prerequisite packages are written first. Package components
		must be listed in PACKAGE.pkg. FORMAT may be one of:
		   cyg  generate a cygwin package
		   exp  generate an exptools(1) maintainer source archive
		        and NPD file in the exp subdirectory, suitable for
			expmake(1); support files are placed in the
			exp/PACKAGE subdirectory
		   lcl	generate a package archive or delta in the lcl
			subdirectory, suitable for restoration into the
			primary source tree (no source licence annotation)
		   pkg	generate a pkgmk(1) package, suitable for pkgadd(1)
		   rpm  generate an rpm(1) package
		   tgz  generate a gzip(1) tar(1) package archive; this is
			the default
		   tst  generate tgz FORMAT package archive in the tst
			subdirectory; version state files are not updated
		The package type must be one of source, binary or runtime.
		A source package contains the source needed to build the
		corresponding binary package. A binary package includes the
		libraries and headers needed for compiling and linking
		against the public interfaces. A runtime package contains
		the commands and required dynamic libraries.  A package may
		be either a base or delta. A base package contains a
		complete copy of all components.  A delta package contains
		only changes from a previous base package. Delta recipients
		must have the ast pax(1) command (in the ast-base package.)
		If neither base nor delta is specified, then the current
		base is overwritten if there are no deltas referring to the
		current base. Only the tgz and lcl formats support delta.
		If base is specified then a new base and two delta archives
		are generated: one delta to generate the new base from the
		old, and one delta to generate the old base from the new;
		the old base is then removed. If delta is specified then a
		new delta referring to the current base is written.
		package.pkg may reference other packages. By default a
		pointer to those packages is written. The recipient package
		read will then check that all required packages have been
		downloaded. If closure is specified then the components for
		all package references are included in the generated
		package.  This may be useful for lcl and versioning.  All
		formats but lcl annotate each source file (not already
		annotated) with a license comment as it is written to the
		package archive using proto(1).
