gir1.2-ags-3.0 binary package in Ubuntu Focal amd64

 libags is a general purpose application context library built upon GObject
 providing persistence and configuration. It allows you to organize threads in
 a tree hierarchy that is synced 1000 times per second per default. Since it is
 written in a object orientated manner you might want to override its default
 behaviour.
 .
 This package can be used by other packages using the GIRepository format to
 generate dynamic bindings.
