Uninstalling Livecode

[RM]

Currently I have about 40 versions of Livecode installed on my Xubun tu 
system, with them all
showing up in the menu system.

This is giving my system "gut rot".

If I dig into the /home/.runrev directory I can manually delete the 
versions I don't want, but the
system still 'sees' those I have deleted, so they show up in the menu 
system.

Is there a way to remove all but the 8 versions I use (3.5, 4.0, 4.5, 
6.7.11, 7.14, 8.0.1, 8.0.2 rc-1 & 8.10) completely?

Richmond.
