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 moz.build 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 moz.build.

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

    Currently `DevToolsModules` can only be called once per moz.build, so we
    build a list manually above.  Bug 1198013 tracks fixing this to make it more
    like other moz.build constructs.'''

    # jar.mn manifest files are typically used to install files to chrome

    # moz.build files to do the installation so that we can enforce correct
    # paths based on source tree location.
