You can browse through the Pivy Mercurial Repository online using the web interface.

Anonymous read-only access is available to everyone. To access the Pivy Mercurial Repository make sure you have a Mercurial client installed on your system. The required Mercurial client can be found at the Mercurial Project page.

The following Mercurial URL needs to be specified to the client: http://hg.sim.no/Pivy/default

An invocation with the Mercurial command line client could look like:

    $ hg clone http://hg.sim.no/Pivy/default Pivy
    requesting all changes
    adding changesets
    adding manifests
    adding file changes
    added 593 changesets with 3032 changes to 938 files
    updating to branch default
    574 files updated, 0 files merged, 0 files removed, 0 files unresolved

Anytime afterwards, to update the Pivy source tree issue:

    $ hg pull -u

in your Pivy source tree.
