If you've never heard of AngbandTk, it's a version of
Angband with a user-friendly interface and souped-up
graphics and sound. It was built by Tim Baker using the
Tcl scripting language. You can download the original from
http://www.thangorodrim.net/download.html#win32

JLETk is so called because it's vanilla AngbandTk plus a
patched version of the "edit" files by Jonathan Ellis,
featuring more monsters, more items a new player race
and a change in monster depths to make diving smoother.
It's considered so good that it was incorporated wholesale
into Angband 3.0.1, for which no Tk release exists.

Note that installing JLETk won't affect any of the other
Tk variants, even though it requires you to paste over
some of the common files with new versions. Characters
from Vanilla AngbandTk should port straight over to the
JLE version without any trouble.​
