# Description:
# Generate some useful statistics from a Raptor build log
# Work out what was specified to make but not built even if
# it was not mentioned in the make error output because some
# child's dependency was not satisfied.
# Needs raptor --tracking option to set make to use -debug=v
# An example bit of make output that can be analysed:
#
