4218885SdimThis directory provides implementations of the lib/System classes that
5218885Sdimare common to two or more variants of UNIX. For example, the directory
6218885Sdimstructure underneath this directory could look like this:
7218885Sdim
8218885SdimUnix           - only code that is truly generic to all UNIX platforms
9218885Sdim  Posix        - code that is specific to Posix variants of UNIX
10218885Sdim  SUS          - code that is specific to the Single Unix Specification
11218885Sdim  SysV         - code that is specific to System V variants of UNIX
12218885Sdim
13218885SdimAs a rule, only those directories actually needing to be created should be
14218885Sdimcreated. Also, further subdirectories could be created to reflect versions of
15218885Sdimthe various standards. For example, under SUS there could be v1, v2, and v3
16218885Sdimsubdirectories to reflect the three major versions of SUS.
