2===========================

4This directory provides implementations of the lib/System classes that
5are common to two or more variants of UNIX. For example, the directory
6structure underneath this directory could look like this:
7
8Unix - only code that is truly generic to all UNIX platforms
9 Posix - code that is specific to Posix variants of UNIX
10 SUS - code that is specific to the Single Unix Specification
11 SysV - code that is specific to System V variants of UNIX
12
13As a rule, only those directories actually needing to be created should be
14created. Also, further subdirectories could be created to reflect versions of
15the various standards. For example, under SUS there could be v1, v2, and v3
16subdirectories to reflect the three major versions of SUS.
