# Script to update Alliance XXX/etc/libraries.mk whith
# the newest libs found in XXX/lib/
# and the newest includes found in XXX/include/.
#
# Creates XXX/etc/libraries.mk.update and gives warnings to stderr
# then copy old libraries.mk to libraries.mk.`date`
# then copy new libraries.mk.update to libraries.mk
#
# Usage :
# Requires 1 arg : XXX which is the path to
# etc/libraries.mk, lib/ and include/
# Eg : update_libraries.mk.sh /users/soft5/labo_pc
