31 # Usage: pre-inst-guile [ARGS]
33 # This script arranges for the environment to support, and eventaully execs,
34 # the uninstalled binary guile executable located somewhere under libguile/,
35 # passing ARGS to it. In the process, env var GUILE is clobbered, and the
36 # following env vars are modified (but not clobbered):
40 # This script can be used as a drop-in replacement for $bindir/guile;
41 # if there is a discrepency in behavior, that's a bug.
