restrict the child’s access to certain applications; and a simple library for
accessing and applying the app filter. This results in the policy being stored

restrict the child’s access to certain applications; a simple library for
accessing and applying the app filter; and a UI program (`malcontent-control`)
for viewing and changing the parental controls settings on users.
The parental controls policy is stored in `/var/lib/AccountsService/users/${user}`,
which is a key file readable and writable only by the accounts-service daemon.
Access to the data is mediated through accounts-service’s D-Bus interface, which
libmalcontent is a client library for.
All the library APIs are currently unstable and are likely to change wildly.

Development
-----------
When developing malcontent, you should be able to run an uninstalled version of
`malcontent-client` or `malcontent-control`, as long as the polkit files from
`accounts-service/` and `malcontent-control/org.freedesktop.MalcontentControl.policy.in`
have been installed system-wide (typically under `/usr/share/polkit-1`) where
your system copy of polkitd can find them.
Dependencies
------------
* accounts-service
* dbus-daemon
* flatpak
* gio-2.0 ≥ 2.60
* gio-unix-2.0 ≥ 2.60
* glib-2.0 ≥ 2.60
