+# 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)
