Fix manpage generation and/or migrate to scdoc
Currently generating the man pages chokes as follows, we should fix that.
I/O error : Attempt to load network entity http://docbook.sourceforge.net/release/xsl/current/manpages/docbook.xsl
warning: failed to load external entity "http://docbook.sourceforge.net/release/xsl/current/manpages/docbook.xsl"
compilation error: file manpage.xsl line 6 element import
xsl:import : unable to load http://docbook.sourceforge.net/release/xsl/current/manpages/docbook.xsl
In addition (or instead of), we can could:
- convert the clunky xml to scdoc
- convert the man pages to html via man2html or mandoc - latter used to generate everything https://man.archlinux.org
