-# This is a script to run a command in ARGV, expanding tabs in some files
-# included by vm.c to normalize indentation of MJIT header. You can enable
-# this feature by passing `--without-mjit-tabs` in configure.
-#
-# Note that preprocessor of GCC converts a hard tab to one spaces, where
-# we expect it to be shown as 8 spaces. To obviate this script, we need
-# to convert all tabs to spaces in these files.
