DESCRIPTION="High-level, high-performance dynamic programming language for technical computing"
HOMEPAGE="http://julialang.org/"
# uses gfortran in some places, dependencies don't reflect that yet
# tarball remade because upstream lacks submodules, so it's not able to build
# soo ... they bundle a split out part of v8 that has no build system that makes sense
# double-conversion nailed in to make build system happy
# dSFMT is not meant to be packaged
