well, that PACKAGE variable is used from within the command line parser 
to print errors, and thus it should be set to the actual command, and 
not to the package name.  However, I think you're right about 
PACKAGE_NAME being useful, for instance when printing the output of 
--help and --version, am I right?

Then probably PACKAGE_NAME should be used to and probably default to 
PACKAGE if not specified, am I right?
