With this verbatim main target rule, I'd expected a t1_cpp.cpp file to
be produced from the t1.verbatim file using the generator,
verbatim.inline-file.  However, --debug-generator showed output:

      *** construct VERBATIM
          from { t1.verbatim.VERBATIM }

so, apparently, the verbatim rule generated by:

import type ;
type.register VERBATIM : verbatim ;

in verbatim.jam has VERBATIM type associated with it instead of the
target type, CPP, in the generator registration:

import generators ;
generators.register-standard verbatim.inline-file : VERBATIM : CPP ;

found also in the verbatim.jam file.

So now the question is, how is a main-target rule defined that will
invoke the verbatim.inline-file action?  I tried defining
verbatim.inline-file rule; however, it did nothing.
