def DevToolsModules(*modules):
    '''Installs JS modules at a resource:// path that corresponds directly to
    their source tree location.

    For this to work as intended, a file should be placed in each
    source directory which uses this template to install only the JS files in
    its own directory.  Subdirectories should use their own

    By following this pattern, there's less magic to require() and resource://
    paths, since they now match the source tree.'''

    # files to do the installation so that we can enforce correct
