     "Suil is a lightweight C library for loading and wrapping LV2 plugin UIs.

Suil makes it possible to load a UI of a toolkit in a host using another
toolkit.  The API is designed such that hosts do not need to explicitly
support specific toolkits – if Suil supports a particular toolkit, then UIs in
that toolkit will work in all hosts that use Suil automatically.

Suil currently supports every combination of Gtk 2, Qt 4, and X11.")
