# 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: uninstalled-env guile -c '(display "hello\n")'
# Example: ../../uninstalled-env ./guile-test-foo
# config
subdirs_with_ltlibs="guile-readline libguile" # maintain me
# env (set by configure)

# $GUILE_FOR_BUILD must use its own source files when booting; for

# path, because it would then end up using its C evaluator to run the
