### Installing

* copy mergetool to a locaton `<pathto>`
* Add this to your .git/config or ~/.gitconfig:

    [merge "po-merge"]
      name = Gettext merge driver
      driver = <patho> %O %A %B

Add this to .gitattributes in some dir:

    *.po   merge=po-merge
    *.pot  merge=po-merge

### Testing

To run the testsuite simply run runtests.py in the topdir.

For each test there is a subfolder in the test dir with folling files:
* base, local and remote - the 3 files for a 3-way merge
* merged - the file after the merge is done
* pot - the corresponding pot file, to get a cleaner picture for sorting and removal context.
        to create such an file run:
            msghack --empty remote > pot

you can simply look into the examples and run diff to see what is done.

### Documentation

I didn't have written the different po merge tools. I found them at the internet :D
