 # This is the main entry point to crosstool

 #   - download, extract and patch the toolchain components

 #   - build and install each components in turn

 #   - and eventually test the resulting toolchain

 # 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.
