description       Isabelle is a popular generic theorem proving environment.
long_description  Isabelle is a generic proof assistant. It allows mathematical \
                  formulas to be expressed in a formal language and provides \
                  tools for proving those formulas in a logical calculus. The \
                  main application is the formalization of mathematical proofs \
                  and in particular formal verification, which includes proving \
                  the correctness of computer hardware or software and proving \
                  properties of computer languages and protocols.

# The goal is to make polyml+isabelle "just work" out of the box. If
# a user wishes to use other implementations of ML, then they will
# have to edit the settings file directly.
#
# The settings file is limited to very few scenarios out of the box.
# We modify the linux entry, since it is the closest thing that will
# resemble our darwinports installation.
