File inclusion should be easy to implement outside the Sgml.pm module.
That's indeed a shame that this is implemented in the module where it's the
more complicated (using an external parser requires a load of bookkeeping to
indicate the right position on error messages) and not in the others.

I guess that we just need a include_file(filename) function in TransTractor=
=2Epm
Its action would be much like the read() function already there. You only
need to read into a new array instead of @{$self->{TT}{doc_in}} Then, when
you got all the file,=20
while (defined(my ($l,$ref) =3D pop @newarray) {
  $self->unshiftline($l,$ref);
}

or so. Ie, insert the content of the new file in the working spaces. I'll do
the trick for all modules using the popline function. Ie, Man.pm and Xml.pm
(for now. One day, Sgml.pm will be in this list).



I hope it makes sense to someone with more free time than me ;) If you want
to proceed and implement this, please go ahead.=20
