3# General notes:
4#
5# A number of Make variables are used to generate the crunchgen config file.
6#
7#  CRUNCH_SRCDIRS: lists directories to search for included programs
8#  CRUNCH_PROGS:  lists programs to be included
9#  CRUNCH_LIBS:  libraries to statically link with
10#  CRUNCH_SHLIBS:  libraries to dynamically link with
11#  CRUNCH_BUILDOPTS: generic build options to be added to every program
12#  CRUNCH_BUILDTOOLS: lists programs that need build tools built in the
13#       local architecture.
14#
15# Special options can be specified for individual programs
16#  CRUNCH_SRCDIR_$(P): base source directory for program $(P)
17#  CRUNCH_BUILDOPTS_$(P): additional build options for $(P)
18#  CRUNCH_ALIAS_$(P): additional names to be used for $(P)
19#
20# By default, any name appearing in CRUNCH_PROGS or CRUNCH_ALIAS_${P}
21# will be used to generate a hard link to the resulting binary.
22# Specific links can be suppressed by setting
23# CRUNCH_SUPPRESS_LINK_$(NAME) to 1.
24#
25# If CRUNCH_GENERATE_LINKS is set to no, no links will be generated.
