annotate gpp/downloads/views.py @ 6:b6263ac72052

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Use DRY principle to manage third party javascript libraries. Created script_tags template tags to generate the correct link and script tags for 3rd party libraries. The settings.py file is the only place where the full path name is specified.
