8 # - build and install each components in turn

12 # options. It also checks the existing environment for un-friendly variables,
13 # and builds the tools.
15 # Parse the common functions
16 # Note: some initialisation and sanitizing is done while parsing this file,
18 # - set trap handler on errors,
19 # - don't hash commands lookups,
