# Script to start cgreen-runner under gdb, load a library and break
# on a named test.
#
# If you are viewing 'cgreen-debug' this *is* that script and you'll
# find the logic at the end of this file. To update it, edit
# `cgreen-debug.argbash` instead.
# But if you are looking at 'cgreen-debug.argbash' then this is
# actually a template for argbash (https://argbash.io) which generates
# argument parsing capable bash scripts from a template just like
# this.
# To generate a new 'cgreen-debug' use
#
# 'argbash cgreen-debug.argbash -o cgreen-debug'
#
# if you have argbash installed, or go to https://argbash.io and paste
# this file into the online version.
