[galaxy-dev] Control on versioning in toolshed tools

Hi All, I am playing around with putting a tool in testtoolshed. Now when changes to dependency versions are detected, the toolshed detects a new version and a dropdown is created. but sometimes I do not want this behavior when the first version was erroneous for example. I tried hg strip on the repository and pushing it back to the testtoolshed but sadly it didn't result in a clean repository but a multi-headered mess. Is there a way to cleanup the remote repository and start over. And what would be a cleaner way to develop tools on a toolshed still making use of repository dependencies? Thanks, Eric
