# This script fixes the fundamental problem of libtool: it is not 
# configurable in run-time.  This changes the libtool so that it becomes
# more generic and configurable in run-time.  It is possible to specify
# how the libtool should behave by environment variables.
#
# Environment variables:
#
# LIBTOOL_ENABLE_SHARED
# LIBTOOL_ENABLE_STATIC
#
# Set either to "yes" or "no" value.  "no" is equivalent to being disabled.
# If environment variables are not given then the default settings apply.
#

# Sanity checks

# configuration of the libtool.  This could include a lot of other
# things like command line arguments too.
