I was looking for a gui for UPX on SourceForge and found UPXcmd. It had been been set up a as .paf.exe back in September, so I decided to try it out.
Turns out it wasn't really PAF compliant as we are using today, so I set about redoing it to make it so.
From the author's readme:
UPXcmd is an open source GUI (Graphical User Interface) for excellent
executable packer, UPX (Ultimate Packer for eXecutables, upx.sf.net).
UPXcmd package contains a new program, UPXcmd DropBox. Dropbox allows
you to compress your files by dragging them to an always on top window.
DropBox uses UPXcmd main program's settings for processing.
I created launchers for both UPXcmd and UPXcmdDropBox.
