Inform is a design system for interactive fiction based on natural language.
It is a radical reinvention of the way interactive fiction is designed, guided
by contemporary work in semantics and by the practical experience of some of 
the world's best known writers of SF.

This includes both the "gnome-inform7" IDE and the "i7" command-line shell.

This requires libsoup (with libsoup-gnome enabled), gtksourceview, goocanvas,
and webkit.
