TortoiseFossil for Fossil SCM
What you'll find here is a work in progress to have a Tortoise-style tool for Fossil repositories. Currently there is no release just yet, there are no commands implemented as of right now, but file overlays are working great.
The repository can be cloned with fossil clone:
fossil clone http://www.tortoisefossil.org/index.cgi TortoiseFossil.fossil
