Hi Eric! Thanks for reporting this!

When you say you have foo-2.0 in the root_dir, do you mean directly under
the $ROOT or in $ROOT/lib??

Please feel free to list the other issues that you regard as bugs, and I
will have a look at it.

Also, there has been a rather big update of reltool including many bug
fixes in the upcoming R15B01, so maybe some of your issues are already
taken care of... :)
