+# Commentary:
+
+# Usage: pre-inst-guile [ARGS]
+#
+# This script arranges for the environment to support, and eventaully execs,
+# the uninstalled binary guile executable located somewhere under libguile/,
+# passing ARGS to it. In the process, env var GUILE is clobbered, and the
+# following env vars are modified (but not clobbered):
+# GUILE_LOAD_PATH
+# LTDL_LOAD_PATH
+#
+# This script can be used as a drop-in replacement for $bindir/guile;
+# if there is a discrepency in behavior, that's a bug.
+
+# Code:
+
+# config
+subdirs_with_ltlibs="srfi guile-readline" # maintain me
+
+# env (set by configure)
