Problem/Motivation
Moving modules into contrib/custom after install doesn't seem to work. According to the documentation, all one has to do if one wants to move modules into a custom or contrib directory structure is mv the directory, and clear the cache. This does not work. In fact uninstalling a module, and installing it in one of these directories doesn't work.
Proposed resolution
Ultimately fix this if it can be fixed, but presently updating the documentation would help alleviate the 'oh crap' feeling of a broken site.
