35: * INSTRUCTIONS:
36: * =============
37: * The following should be handled in the Makefile:
38: * For USG Unix, define USG; for BSD Unix, don't (see ifdef USG).
39: * For 4.2 bsd, define V4_2BSD; this will replace the routines
40: * getwd() and rename() with the corresponding ones in the C-library.
41: * V4_2BSD also selects different definitions for the macros NCPFN and NCPPN
42: * (max. number of characters per filename, number of characters per path name).
43: * Define STRICT_LOCKING appropriately (see STRICT_LOCKING).
44: * The following need be changed for porting to a different machine:
45: * Define SMALLOG for a machine with small memory (like the PDP11).
46: * SMALLOG conserves space for log messages.
47: * Change BYTESIZ if necessary.
48: * If you need to change the comment leaders, update the table comtable[]
49: * in rcsfnms.c. (This can wait until you know what a comment leader is.)
