This our Debianization of libmypaint as an indepdendent package. It is maintained in a separate module to give you the option of making your own.
To use it, check out the relevant branch of libmypaint, then drop this
repository into it under the name debian:
git clone https://github.com/mypaint/libmypaint.git
cd libmypaint
git clone https://github.com/mypaint/libmypaint.deb.git debian
The usual Debian-style build trickery should then work if you have the right dependencies:
fakeroot debian/rules binary
This repository is the basis for our PPA builds of libmypaint.
