Script and .desktop file for custom termlink:// protocol links.
The handler can be configured to do anything with such a link, but usually opens the referenced file in your preferred editor.
Put the termlink script into your path. Copy the termlink.desktop file to the $XDG_DATA_HOME/applications directory.
Copy the termlink.conf to $XDG_CONFIG_HOME/termlink/config and edit it to your liking.
