For all you die-hard UNIX hacks that
know vi is the only way to edit, and are stuck working in
Windows®,
try Lemmy, a
really cool vi clone.
I've finally found a Windows® port of
the GNU-RCS revision control
system worth using. It is called CS-RCS from Component Software. It is
lacking a couple features, but the shell integration is excellent.
There is even a freeware personal version (which I use as a lone
programmer). Check it out!
