Config::model::tkui provides a perl/tk interface to:
- the configuration editor provided by config::model (cme).
- the configuration model editor provided by config::model::itself
(config-model-edit)
for instance, with this package and libconfig-model-openssh-perl config::model::openssh, you get a graphical configuration editor for /etc/ssh/sshd_config.

to get the graphical editor, just install config::model::tkui, and the cme (provided by libconfig-model-perl) will automagically launch the graphical interface.
