rem   YOU'LL NEED THE FOLLOWING UTILITIES TO MAKE EMACS:
rem
rem   + msdos version 3 or better.
rem   + djgpp version 1.12maint1 or later (version 2.0 or later recommended).
rem   + make utility that allows breaking of the 128 chars limit on
rem     command lines.  ndmake (as of version 4.5) won't work due to a
rem     line length limit.  The make that comes with djgpp does work.
rem   + rm and mv (from GNU file utilities).
rem   + sed (you can use the port that comes with DJGPP).
rem
rem   You should be able to get all the above utilities from any SimTel
rem   repository, e.g. ftp.coast.net, in the directories
rem   "SimTel/vendors/djgpp" and "SimTel/vendors/gnu/gnuish/dos_only".  As
rem   usual, please use your local mirroring site to reduce trans-Atlantic
rem   traffic.
