# 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_LIBRARY_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 libguile" # maintain me
# env (set by configure)
top_srcdir="@top_srcdir_absolute@"
top_builddir="@top_builddir_absolute@"
