# Usage: pre-inst-guile-env [ARGS]
# This script arranges for the environment to support running Guile
# from the build tree. The following env vars are modified (but not
# clobbered): GUILE_LOAD_PATH, LTDL_LIBRARY_PATH, and PATH.
# Example: pre-inst-guile-env guile -c '(display "hello\n")'
# Example: ../../pre-inst-guile-env ./guile-test-foo
# config
subdirs_with_ltlibs="srfi guile-readline" # maintain me
# env (set by configure)
