=head1 NAME
genencoding - generate encoding test samples
=head1 SYNOPSIS
C<genencoded> I<encoding> ...
Generate test (or sample) documents that demonstrate and test
the given encodings, in the LaTeXML t/encoding directory.
Since the coverage, completeness or even correctness of the
encoding definitions changes from one TeX release to another,
you may occasionally find it necessary to manually delete some cells
from the generated table to make the test case more portable.
