How to install
To install a style just place its xml-file into a folder of the style search path.
A typical search path for Gtksourceview-2 looks like:
1. ~/.local/share/gtksourceview-2.0/styles/
2. /usr/share/gnome/gtksourceview-2.0/styles/
3. /usr/local/share/gtksourceview-2.0/styles/
4. /usr/share/gtksourceview-2.0/styles/
If this does not work in your distribution you can find out your style search path
with this python script. To run it you need the python bindings for Gtksourceview-2.
In Debian-based distributions this is package "python-gtksourceview2".
