# The Rodin runtime requirements track sci-mathematics/rodin (>=virtual/jre-17:*
# and x11-libs/gtk+:3): here the JRE is raised to a JDK because the headless
# builder plugin is compiled on the fly with javac, and Xvfb is added because
# SWT still needs a display when Rodin runs headless. zip/unzip repackage the
# model archives while curl and tar fetch and unpack the Rodin and ProB
# runtimes, which rodin-headless-install downloads into a per-user data dir on
# first use rather than this package shipping them.
