[GRLUG] Mac & ??: reverse-URL file and directory names

[Eric Beversluis]

I've come across this occasionally and see it on my Mac--eg, under
Library/Cache: directory and file names that look like reverse urls:

com.barebones.textwrangler
or 
com.adobe.ARM

I'm not even clear how I would Google for an explanation of when and how
and why this naming convention is used. E.g., if we're naming files on a
computer with no internet connection, why start with 'com'? etc.

Thanks.
