[galaxy-dev] Developing package wrappers

Hi, I am afraid that I might be overlooking something obvious but... I am trying to add a few tools to the RAD-Seq portfolio of Galaxy. For that effect I am designing a few package wrappers. My problem is to understand the best practice to develop wrappers for dependencies of external tools. For normal tools, that is quite easy: one uses the galaxy/tool/XXX to do all development and testing. But for dependency wrappers, the only solution that I have found is to upload the wrapper to a toolshed and installing it via the admin interface... This is cumbersome. Is there any way to test/develop a package wrapper so that I can test tool_dependencies.xml without uploading it to a toolshed and installing it from there? Thanks, Tiago
