Thanks for explaining.  So as I understand it, it is for installing public
Perl modules, as would be installed by a MakeMaker build system (a frequently
used build system for Perl).  In order to match how Perl modules are usually
installed, these directories should be configurable.  There seemed
to be a module called Texinfo.pm which was built under tta/swig/perl/
which is probably what this is for.

I don't understand any more (and hope that I won't need to understand any
more, as there is a limit to how much time and attention I can give to such
issues).

The only suggestion I have to make this slightly tidier is to move the
options to the end of the --help message to keep them separate from the
other options.
