gmuck assists you in producing valid (X)HTML by checking CGI scripts, XSL stylesheets, templates, normal HTML files or [you name it] and reporting errors that it finds. It is not a replacement for real validation tools, but is handy in quick checks and in situations where validation of the actual markup is troublesome.
Take a look at the README file included in the distribution for more
documentation. HTML versions of the manual pages are also available;
start from the
gmuck manpage and
check out the
HTML::GMUCK manpage too.
For more information, head to the SourceForge project page.
Source tarballs are available from SourceForge and CPAN,
and an RPM package can be built from the tarball with
rpmbuild -tb (tested on Fedora Core only).
