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

+ * 4.2 prerelease
+ *
+ * Revision 3.6 83/01/15 16:43:28 wft
+ * Replaced dbm.h with BYTESIZ, fixed definition of rindex().
+ * Added variants of NCPFN and NCPPN for bsd 4.2, selected by defining V4_2BSD.
+ * Added macro DELNUMFORM to have uniform format for printing delta text nodes.
+ * Added macro DELETE to mark deleted deltas.
+ *
+ * Revision 3.5 82/12/10 12:16:56 wft
+ * Added two forms of DATEFORM, one using %02d, the other %.2d.
+ *
+ * Revision 3.4 82/12/04 20:01:25 wft
+ * added LOCKER, Locker, and USG (redefinition of rindex).

+ * Revision 3.3 82/12/03 12:22:04 wft
+ * Added dbm.h, stdio.h, RCSBASE, RCSSEP, RCSSUF, WORKMODE, TMPFILE3,
+ * PRINTDATE, PRINTTIME, map, and ctab; removed Suffix. Redefined keyvallength
+ * using NCPPN. Changed putc() to abort on write error.
+ *
+ * Revision 3.2 82/10/18 15:03:52 wft
+ * added macro STRICT_LOCKING, removed RCSUMASK.
+ * renamed JOINFILE[1,2] to JOINFIL[1,2].
+ *
+ * Revision 3.1 82/10/11 19:41:17 wft
