Git Repository Instructions
The latest version of the plugin package can be found in a git repository. Of course, you will need to have git installed on your system.
The git repository page is here.
Getting the sources
The first time, just issue:
git clone git://repo.or.cz/gimp-lqr-plugin.git
This will create a directory called gimp-lqr-plugin under your current directory, with the package main tree.
You can then enter into it and compile and install it, following the instructions you find at this page.
Later, you can update it by issuing:
make distclean
git pull
from inside the plugin directory.
