**  fix executables and installation locations for Hugs

**  only create the installedConfigFile if the package has a buildable library.

** Regularize treatment of --verbose:
  
  * no longer a global option (it was ignored there)
  
  * added to configure and clean, so it's an option for all commands
  
  Also fixed the Usage message and clobbered placeholder long descriptions.
