collect: symbolic link storage
- Adds a symbolic link storage for developers. To enable it, put this to your config: COLLECT_STORAGE = u"invenio.ext.collect.storage.link" then run inveniomanage collect to create all the links from the static folders to the intance folder.
- NOTE: only files are symlinked, not folders!
