| 2 | =========================== |
| 3 | |
| 4 | This directory provides implementations of the lib/System classes that |
| 5 | are common to two or more variants of UNIX. For example, the directory |
| 6 | structure underneath this directory could look like this: |
| 7 | |
| 8 | Unix - 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 | |
| 13 | As a rule, only those directories actually needing to be created should be |
| 14 | created. Also, further subdirectories could be created to reflect versions of |
| 15 | the various standards. For example, under SUS there could be v1, v2, and v3 |
| 16 | subdirectories to reflect the three major versions of SUS. |
