contrib - Contribution Guidelines for MRTG


If you have written an extension to mrtg or created a bug fix, please consider contributing it to the project. As I get quite a number of contributions every week, here are a few guide lines which explain how to contribute so that I can use the contribution without too much additional work.


MRTG messages have been translated to a number of languages. But there are still many which have not been covered yet. If you want to add yours, go into the mrtg-2.9.25/translate directory, and follow the instructions given in the README file.


All documentation of mrtg is done with the perl POD system. If you want to learn about it, type

 perldoc perlpod

and read the instructions. If you have bugfixes of additions to the existing documents, make sure you modify the POD files and not the html or txt versions.


When you have created your modification or extension to mrtg and want to submit it to me, please crate a patch for the files which you have modified. Do not send entire files unless they are new.

To create a patch, get hold of a copy of GNU diff (Many Unix systems will have this installed already. In the NT world you might want to get to get all the nice GNU tools available.) and type

 diff --unified --ignore-space-change old-file new-file > simple.patch

or if you have modified several files do

 diff --recursive --unified --ignore-space-change old-dir/ new-dir/ >long.patch


I take documentation very seriously. Whenever you create a new feature for mrtg which you want to get included in the official release your patch must also contain modifications for the relevant pod file in the doc tree or for the documentation sections of cfgmaker and indexmaker.
