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