You don't use files?  You're telling me that instead of copying & 
modifying my friend's bashrc, I should be querying a bunch of tables 
with SQL?  Bull.  Ordinary files, preferably in line-separated or tagged 
formats, are going to be a lot easier for most of us to work for a long 
time to come.  This is especially true now that we have lots of good 
libraries for working with XML-based formats.
