# 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:

#
