     5 # This is the main entry point to crosstool
     6 # This will:
     7 #   - download, extract and patch the toolchain components
     8 #   - build and install each components in turn
     9 #   - and eventually test the resulting toolchain
    10 
    11 # What this file does is prepare the environment, based upon the user-choosen
    12 # options. It also checks the existing environment for un-friendly variables,
    13 # and builds the tools.
    14 
    15 # Parse the common functions
    16 # Note: some initialisation and sanitizing is done while parsing this file,
    17 # most notably:
    18 #  - set trap handler on errors,
    19 #  - don't hash commands lookups,
    20 #  - initialise logging.
