filebrowser_safe is a permanent fork of FileBrowser asset manager for Django, to be referenced as a dependency for the Mezzanine CMS for Django.
At the time of filebrowser_safe's creation, FileBrowser was incorrectly packaged on PyPI, and had also dropped compatibility with Django 1.1 -- filebrowser_safe was therefore created to address these specific issues.
For further details, see Why are Grappelli and Filebrowser Forked?.
