# Responsibilities of this file:
# - create GOPATH in _build with symlink to current dir
# - re-generate _build/Makefile from makegen.go on each run
# - dispatch commands to _build/Makefile
#
# "Magic" should happen in the makegen.go dynamic template. We want
# _build/Makefile to be as static as possible.
