+# 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).
