File::Find lacks the "making easy things easy" part, so modules like this are great. A further step would be an option to omit $wanted for even simpler cases, but that would probably break the interface. Another alternative is File::Finder, but it forces OO style.
The Synopsis is clear enough that I was able to use this several years ago as a Perl neophyte, despite not knowing what a callback was.
As Andy mentions in the Synopsis, if you really do need a set of complex rules to identify the files you want, check out File::Find::Rule. However, nine times out of ten, you probably don't need anything more than the ease and simplicity of File::Find::Wanted.
