# A simple debug function that can be used inside shell scripts to pause
# execution and allow for inspection of the environment and execution of
# commands.

# Example usage in a script:

#    #! /usr/bin/env bash
#    # Load the debug function
#    source scripts/functions/debug.sh
#
#    ...
#
#    # Then use it somewhere
#    foobar() {
#        debug # Now I can inspect the variables that were passed into foobar
#    }
