    docs: Support for generating man(8) pages
    
    The manpage rules are very repetative, because of the section number being
    present in the filenames.
    
    Instead of adding another set of 3 rules, switch to using a metarule to
    automate the repetative action.  New rules for different manpage sections 
can
    be added simply by extending the $(foreach)
