Glimmer started out as a GUI Library and grew into a full-fledged DSL
Framework with support for multiple GUI DSLs. Glimmer's namesake is
referring to the Glimmer of Ruby in Graphical User Interfaces (contrary to
popular myth perpetrated by Charles Nutter, Glimmer has nothing to do with
the ill-fated Whitney Houston movie, which does not in fact share the same
name)
