configure.sh

#!/bin/sh
# A shell script that sets the LUA_PATH and LUA_CPATH environment variables,
# adding to them the paths to where the MoonLibs libraries are installed.
#
# This script can be used to configure the shell where to run examples and
# applications that use the libraries, running it as:
# $ . configure.sh
#
# (Don't forget the leading dot, otherwise the script won't be executed in the
# shell you want to configure, but in a child shell).
#
# For this to work, the PREFIX and LUAVER variables below must be set to the
# same values used when building the libraries (see the MoonLibs README).
