I tried out byecycle.  It looks pretty good.  Our project is old and
massive, so it doesn't seem like a good fit.  After uninistalling, I
get an error with CVS: "Resource /<projectname>/.byecycle is not
local.  It doesn't look like the plugin cleaned up after itself.

Any ideas?  Or, will I have to create a new workspace?  There are
artifacts in .plugins\org.eclipse.core.resources\.root\80.tree
and .plugins\org.eclipse.ui.workbench\workbench.xml of my workspace.
Editing the xml is easy enough.  But, editing the 80.tree file
directly is ill-advised.

Thanks,

Lemur

For now, have you tried simply deleting the .byecycle directories?
