## Global variables. ##

## ----------------- ##

# Except for the global variables explicitly listed below, the following

# functions in the '^func_' namespace, and the '^require_' namespace

# variables initialised in the 'Resource management' section, sourcing

# this file will not pollute your global namespace with anything

# else. There's no portable way to scope variables in Bourne shell

# though, so actually running these functions will sometimes place

# results into a variable named after the function, and often use

# temporary variables in the '^_G_' namespace. If you are careful to

# avoid using those namespaces casually in your sourcing script, things

# should continue to work as you expect. And, of course, you can freely

# overwrite any of the functions or variables defined here before

# calling anything to customize them.
