;** indenth.m:
;** Templates for Fortran and Modula-2. To use them, just use Setup
;** to turn template editing on for Fortran and/or Modula-2, and
;** start BRIEF with the -mindenth flag.
;** Sample BPACKAGES=for,mod:t;c:s;m,h,asm:r
;**
;** Note: these have been converted to BRIEF v2.0, but they do not
;** support any more constructs than they did under BRIEF v1.3.
;**
#define SEMI_COLON 1 ;** Code for semicolon.
#define MIN_ABBREV 1 ;** Increase this to specify longer
;** minimum abbreviations.
