# This Makefile is a wrapper around chicken-install(1) which eases building
# edward without superuser rights and without requiring any configuration
# of chicken-install. Furthermore, it supports optional dependency vendoring
# to build edward without network access.

# By default, the Makefile builds a statically linked binary. For development
# purposes it can be desirable to do dynamic linked builds instead. To do so
# the PACKAGE environment variable can be set to zero.
