For example, the directory 6*f4a2713aSLionel Sambucstructure underneath this directory could look like this: 7*f4a2713aSLionel Sambuc 8*f4a2713aSLionel SambucUnix - only code that is truly generic to all UNIX platforms 9*f4a2713aSLionel Sambuc Posix - code that is specific to Posix variants of UNIX 10*f4a2713aSLionel Sambuc SUS - code that is specific to the Single Unix Specification 11*f4a2713aSLionel Sambuc SysV - code that is specific to System V variants of UNIX 12*f4a2713aSLionel Sambuc 13*f4a2713aSLionel SambucAs a rule, only those directories actually needing to be created should be 14*f4a2713aSLionel Sambuccreated. Also, further subdirectories could be created to reflect versions of 15*f4a2713aSLionel Sambucthe various standards. For example, under SUS there could be v1, v2, and v3 16*f4a2713aSLionel Sambucsubdirectories to reflect the three major versions of SUS. 17
