To come +up with names is hard, and testing to ensure they're not already in use is +time-consuming - unless you have a tool such as this one. + +=head1 CUSTOMIZATION + +The script, as is, contains a list of sites, and patterns, to test against. + +If those patterns aren't sufficient then you may create your own additions and +add them to the script. If you wish to have your own version of the patterns +you may save them into the file ~/.namecheckrc + +=head1 AUTHOR + +Steve +-- +http://www.steve.org.uk/ + +=head1 LICENSE + +Copyright (c) 2008 by Steve Kemp.
