You can contribute to Bersirc by checking out sources from SubVersion, creating a patch file and sending it to us.
SubVersion provides a way to generate patches against the checked out sources without needing 2 copies (which would be needed to use "diff"). TortoiseSVN has the option by right clicking on the file or the root of the sources and selecting "Create Patch" under the TortoiseSVN menu. Using the console version, you can type "svn diff > mychanges.patch" in the source directory.
Please let us know if you're fixing a bug by commenting on the bug report page. This stops duplicate work.
Consider also joining us in the #Bersirc channel
so everyone knows who's contributing. It will also increase chances of
becoming a team member (developer). We add people to the team when they
contribute a significant amount of patches to Bersirc and/or Claro.
