''Test/Apply a patch''
If you want to apply a patch file on an old version to have a new one modified by the path file, this is possible with the '''patch''' tool.
Imagine you have on non modified version somewhere on a server. Put you patch file into the root directory. Go into this root directory then launch the command:
''Send patch by mail''
Once patch file is built and successfully tested, you must submit file to the Dolibarr mailing list '''dolibarr-dev''' (See here for this https://savannah.nongnu.org/mail/?group=dolibarr).
This mailing list is read by most Dolibarr developers, however we can't say if path will be processed nor that it will be included. It depends on quality of patch and priorities of moment.
