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.

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 the DJGPP FTP
