-JA2 UB tilesets for JA2.
-Snap <tacpans@yahoo.com>
-
-This package contains files that are necessary to import maps using JA2 UB
-tilesets #50-59 into JA2.
-
-Installation: Unpack the archive into the JA2 main directory.  The files will be
-unpacked into Data-1.13 subdirectory.  If you are using a different custom data
-directory, you need to move all of the included files and subdirectories there:
-
-Binarydata\ja2set.dat
-Tilesets\50
-...
-Tilesets\59
-
-Notes:
-
-This add-on will only work in JA2 1.13, or any version of JA2 that has been
-modified to accept tilesets with numbers 50 or higher.  Alternatively, the UB
-tilesets can be used to replace existing JA2 tilesets (for that, ja2set.dat
-needs to be modified accordingly).
-
-Maps created with the UB editor or original UB campaign maps need to be
-converted to JA2 format first.
-
-In tilesets 53-59 snow-covered graphics, such as sandbags, were replaced with
-more appropriate JA2 graphics.
