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. 17
