The purge command removes content from a repository and stores that content in a "graveyard". The graveyard exists so that content can be recovered using the "fossil purge undo" command. The "fossil purge obliterate" command empties the graveyard, making the content unrecoverable.

WARNING: This command can potentially destroy historical data and leave your repository in a goofy state. Know what you are doing! Make a backup of your repository before using this command!

FURTHER WARNING: This command is a work-in-progress and may yet contain bugs.
