# WARNING: this barely works.
# Notes: 

# pyethereum in AUR is very out of date, should be updated
# pyethereum-git depends on many orphaned packages, and doesn't work either
# Thus, pyethereum had to be installed from pip

# python2-docker - 2.x has been released, incompatible, so had to install from pip
