Git: creating and importing patches

A useful command when you need to contribute to open source projects:
1. Create a patch from your last commit (-n for the n latest commits). The following command will create a <myKillerPatch>.patch file in the current directory

   git format-patch -1

2.  Test the patch

   git apply --check <myKillerPatch>.patch

3. Finalyy import it

   git am <myKillerPatch>.patch
