# What this file does is prepare the environment, based upon the user-choosen

# options. It also checks the existing environment for un-friendly variables,

# and builds the tools.

# Parse the common functions

# Note: some initialisation and sanitizing is done while parsing this file,

# most notably:

#  - set trap handler on errors,

#  - don't hash commands lookups,

#  - initialise logging.
