The static site checker nitpicks static web sites and HTML snippets.
It is intended for people, like its author, who hand code websites.
It doesn’t just check static sites for broken links, dubious syntax, and bad semantic data, it will actively complain about things that are perfectly legal but rather untidy—like its author.
Except when serving CGI queries, it recursively scans your chosen directory seeking HTML & related files to verify. It produces a list of errors, warnings, and other hints of imperfection. Scripts are ignored.
It should not be used on untrusted content; its parsers are holier than Robin’s cow .
