    (description "Idris is a general purpose language with full dependent
types.  It is compiled, with eager evaluation.  Dependent types allow types to
be predicated on values, meaning that some aspects of a program's behaviour
can be specified precisely in the type.  The language is closely related to
Epigram and Agda.")
