=head1 DESCRIPTION

This script preprocesses LaTeX document.  This script is
written to satisfy author's need only.

=item Replacement of COMMA and FULL STOP

In science community, use of COMMA and FULL STOP, rather than

This filter script substitutes IDEOGRAPHIC COMMA and IDEOGRAPHIC FULL STOP
to COMMA and FULL STOP, followed by a SPACE.

This filter script puts content of external plain text file
as C<verbatim> block, in place <\sourcecode> pseudo-command happens.
