''' Replaces the tk file dialogs on Linux with external
calls to the zenity gtk dialog package.
This plugin is more a proof of concept demo than
a useful tool. The dialogs presented do not take
filters and starting folders can not be specified.
Despite this, some Linux users might prefer it to the
tk dialogs.
