3 # Name : build variable calculator
4 # Author : Chris Koeritz
8 # This script sets up all the variables needed by the HOOPLE system for
9 # building the source code. It can either be run as a bash script directly
12 # bash ~/feisty_meow/scripts/generator/build_variables.sh
14 # which will establish a new shell containing all the variables, or you can
15 # 'source' the script like so:
17 # build_vars=~/feisty_meow/scripts/generator/build_variables.sh
18 # source $build_vars $build_vars
20 # to set all of the variables in your current shell. The full path is
21 # necessary in these commands to allow the script to easily find itself.
22 # The 'source' version needs to be fed the actual path to the script
23 # because bash 'source' commands cause the first parameter (called $0) to
24 # be set to just the path to bash itself.
