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

Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
