# Usage: build-env [ARGS]
# This script arranges for the environment to support running Guile from
# the build tree. Unlike uninstalled-env, we clobber the environment so
# as to avoid inheriting environment variables that could make Guile
# load .scm, .go, or .so files from installed directories.
# Example: build-env guile -c '(display "hello\n")'
# Example: ../../build-env ./guile-test-foo
