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 2.03 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 (and is

rem     recommended).

rem   + rm, mv, and cp (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 the DJGPP FTP

rem   site, ftp.delorie.com, in the directory "pub/djgpp/current/v2gnu".
