Fixed yet another bug with installation directories, in which the
'install_base' parameter wasn't being respected on the command
line. [Spotted by Jonathan Swartz]Now we don't build man pages when there's nowhere to install them,
such as on some Win32 or most Mac systems.Improved comparisons of version strings containing underscore
characters (indicating "beta" status). [Steve Purkis]Added documentation for the 'dist_author', 'dist_abstract', and
'codebase' parameters to new(), and for the 'ppd' action. [Dave
Rolsky]Added documentation for the up_to_date() and contains_pod()
methods. [Dave Rolsky]'traditional' pass-through Makefile.PLs will now contain an
INSTALLDIRS parameter matching the Build.PL's.
