These file manager extensions are intended to provide integration
with popular GTK+ file managers and the font-viewer component
of font-manager. While the font-viewer is open you should be able
to preview font files simply by selecting them.
To install, copy the extension to one of the following directories.
You may need to create the directory if it doesn't exist.
If you installed the extension to a system directory, compile the extension
python -m compileall /usr/share/nautilus-python/extensions/
python -O -m compileall /usr/share/nautilus-python/extensions/
Nautilus python bindings are available on most distributions.
For Thunar python bindings
Ubuntu/Debian users can find thunarx-python in the RabbitVCS PPA.
For Nemo python bindings
Ubuntu/Debian users *may* need to create a symbolic link to prevent Thunar from crashing.
sudo ln -sf /usr/lib/i386-linux-gnu/libpython2.7.so.1 /usr/lib/libpython2.7.so.1.0
This is not an issue specific to this extension.
