/* Settings storage works as follows:

* It's somewhat tricky to manage the profiles/ dir since we need to track
* the list of profiles, but GSettings doesn't have a concept of notifying that
* a directory has appeared or disappeared.
*
* Session state is stored entirely in the RestartCommand command line.
*
* The number one rule: all stored information is EITHER per-session,
* per-profile, or set from a command line option. THERE CAN BE NO
* OVERLAP. The UI and implementation totally break if you overlap
* these categories. See mate-terminal 1.x for why.
*
* Don't use this code as an example of how to use GSettings - it's hugely
* overcomplicated due to the profiles stuff. Most apps should not
* have to do scary things of this nature, and should not have
* a profiles feature.
