XSLT to turn proper XHTML documents into man pages. Also contains a sample shell script to convert poorly-formatted (X)HTML into something that at least won't blow up the XSLT processor.

Apply the stylesheet like you would any other stylesheet, e.g. with xsltproc(1):

$ xsltproc xhtml2man.xslt input.xhtml > output.7

Alternatively, use the sh/html2man sample script, which will filter stuff using xsltproc after applying cleanups using tidy(1) and possibly even downloading the source (X)HTML using curl(1). For more information, use...

$ man html2man

... after installing the package. Example usages would be:

$ cat input.xhtml | html2man > output.7
$ html2man -i input.xhtml > output.7
$ html2man -r -i http://en.wikipedia.org/wiki/man_page > output.7

Use the supplied makefile, like this:

# make install

The paths where the makefile will put things are customisable. See the makefile for more details, but in particular...

# make install DESTDIR=/some/custom/base/path
