# The standard set of gems in nixpkgs including potential fixes.
#
# The gemset is derived from two points of entry:
# - An attrset describing a gem, including version, source and dependencies
# This is just meta data, most probably automatically generated by a tool
# like Bundix (https://github.com/aflatter/bundix).
# {
# name = "bundler";
# version = "1.6.5";
# sha256 = "1s4x0f5by9xs2y24jk6krq5ky7ffkzmxgr4z1nhdykdmpsi2zd0l";
# dependencies = [ "rake" ];
# }
# - An optional derivation that may override how the gem is built. For popular
# gems that don't behave correctly, fixes are already provided in the form of
# derivations.
#
# This seperates "what to build" (the exact gem versions) from "how to build"
# (to make gems behave if necessary).
