Script for using neroAacEnc and neroAacTag with rubyripper

[Joseph Lenox <lordofhyphens@gmail.com>]

I knocked out a shell script for ripping audio CDs with rubyripper, 
spent entirely too much time on it (forgot that eval takes care of f%^$ 
shell quotes) and finally ended up using foobar2k in a windows VM 
(because foobar's tagger is less hassle for me to work with than 
rubyripper (especially for stuff like disc #, etc), but I'd hate to 
waste this.

It assumes that neroAacEnc and neroAacTag are in the path (because I 
keep my copies in /usr/local/bin).

# Shell script to interface with neroAacEnc and neroAacTag for tagging 
of AAC files.
# Basically put all neroAacTag options and neroAacEnc options on the 
command line, script
# sorts out the two based on the presence of the -meta prefix for the tab.
