  26 # This script arranges for the environment to support running Guile
  27 # from the build tree.  The following env vars are modified (but not
  28 # clobbered): GUILE_LOAD_PATH, LTDL_LIBRARY_PATH, and PATH.

  30 # Example: pre-inst-guile-env guile -c '(display "hello\n")'
  31 # Example: ../../pre-inst-guile-env ./guile-test-foo
