Message:

Some maintenance; no changes to the actual source. Moved the compression tables out of the compression script and into the source file, making the compression script source agnostic. And thus moved the compression script to the Tools directory.

File:

• trunk/Tools/StringsCompress.pl (moved) (moved from trunk/XTIDE_Universal_BIOS/Src/StringsCompress.pl ) (5 diffs)
