Netbeans Linux and Windows Makefile-*.mk and Package-*.bash files in nbproject directories are automatically generated during compile.

This file as documentation (which seems lacking) states is used for calling custom Maven goals from the IDE.
Ignoring this file was a source much confusion in few projects (mapping Run action to custom goals... etc etc)
