This is the ''best method'' to work to build such a patch file:
- First, you must have a directory containing last reference version of Dolibarr (the result of a GIT update or simply the files resulting of uncompressing a dolibarr.tgz snapshot). We will call this directory '''old_dir'''. You can get this snapshot for current
developed version on [http://www.dolibarr.org/downloads/ Dolibarr official web site in download area - development version].
- Then, you must have a second directory, from same source, that will contains Dolibarr directories, in which you will make all you files. We will call this directory '''new_dir'''.
