You can hand the man(1) command the pathname to the *roff file and it
will format it to display it.  So the makefile would not have to do
anything.  But with XML, that isn't the case.

I think that the build process might customize some paths shown in man 
pages.  If so, that would be something not be handled by the man command.  
Likely not a serious problem.
