Ushrink

Ushrink is a command line utility to uncompress sidedefs in WAD files that were compressed by Dshrink. It was written in 1998 by Jim Flynn and ran in DOS. Eric James Roberts (Ricrob) published the executable on his Doomworld-hosted web page. It was also available for download on Doomworld's "Editors & Utilities" section.

The utility will uncompress level sidedefs to allow level editors to update the WAD file.
