/* CHGFILE - changes an old macro file into a new one
   This macro changes a version 1.1 ME macro file into a version
   1.2 macro file. The two changes are
     1) %define => #define
     2) old style comments (# <text>) into C-style comments (/*...)
   After you load this file in, go to the first line and press ALT C.
