   7:  * INSTRUCTIONS:
   8:  * =============
   9:  * The following should be handled in the Makefile:
  10:  *     For USG Unix, define USG; for BSD Unix, don't (see ifdef USG).
  11:  *     For 4.2 bsd, define V4_2BSD; this will replace the routines
  12:  *     getwd() and rename() with the corresponding ones in the C-library.
  13:  *     V4_2BSD also selects different definitions for the macros NCPFN and NCPPN
  14:  *     (max. number of characters per filename, number of characters per path name).
  15:  *     Define STRICT_LOCKING appropriately (see STRICT_LOCKING).
  16:  * The following need be changed for porting to a different machine:
  17:  *     Define SMALLOG for a machine with small memory (like the PDP11).
  18:  *     SMALLOG conserves space for log messages.
  19:  *     Change BYTESIZ if necessary.
  20:  * If you need to change the comment leaders, update the table comtable[]
  21:  * in rcsfnms.c. (This can wait until you know what a comment leader is.)
