#  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.

#  that class has all the interesting logic, and we only need
#  to override the 'pattern' method which return regular
#  expression to use when scanning.

# the property which specifies the search path
# for includes.

# To test this, build the project, touch the
