In order to contribute to MondoRescue, you have multiple ways:

• First, edit the Wiki and improve its content
• Second send patches on the MondoRescue [mondo-devel_at_lists.sourceforge.net Mailing-List] to get them discussed, approved and applied.
• Third, once you've proved your ability to provide good patches, ask to become official contributor by sending your public SSH key to the {​mailto:bruno_at_mondorescue.org maintainer]
• Once accepted as maintainer, you can access to the repository in write mode using the following CLI:

  $ mkdir mondorescue
  $ cd mondorescue
  $ svn co svn+ssh://mondorescue@mondo.hpintelco.org/branches .
  $ svn co svn+ssh://mondorescue@mondo.hpintelco.org/devel .
  

Not that currently, the stable branche is 2.2.9 (which is then declined into 2.2.9.1, 2.2.9.2 - tags available as well) If you modify 2.2.9, please also apply your modification to the next branch, 2.2.10 at the moment.

A third tree (devel) is usedd for experimental stuff on mondorescue, including the perl rewrite, and shouldn't be used for the moment. A fourth tree (trunk) was an attempt to rewrite mondorescue to only use dynamic memory allocation. Most of that work is now in 2.2.10 and it should be considered dormant.
