I've made a .deb for ReNamer as well: ReNamer .deb
Installation, usage, etc:
Install via: sudo dpkg -i debfilename
Run via: renamer
Uninstall via: sudo apt-get remove renamer
After running renamer for the first time, a subdirectory should be created under your home directory named .renamer. After uninstallation, you may want to delete this subdirectory but possibly keep (backup) any settings that may be in that directory.
