Usage: #{opt.program_name} 

kindle-feeds reads a feed list from #{CONFIGFILE}.conf, downloads the feeds, and
generates a Kindle-compatiable and optimized HTML file that can be sent to 
[email protected] or [email protected] for conversion 
into an .azw file for reading on the Kindle. 

The first time kindle-feeds is run, it will generate a stub #{CONFIGFILE}.conf file
in the same directory. Please edit this file to specify the feeds you want to
download and convert for Kindle reading. Further instructions can be found at the
top of kindle-feeds.conf once it is generated.
