#  Each part has a comment describing its purpose, and you can pick the parts
#  which are relevant to your case, remove everything else, and then change names
#  and actions to taste.

#  Declare a new target type. This allows Boost.Build to do something sensible
#  when targets with the .verbatim extension are found in sources.

#  First, define a new class, derived from 'common-scanner',
#  that class has all the interesting logic, and we only need
#  to override the 'pattern' method which return regular
