Description:
Advanced Gtk+ Sequencer core library (API documentation)
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 contains the API reference in html format of Advanced Gtk+ Sequencer base library.
