=head1 ABOUT

  Chronicle is a simple tool to convert a collection of text files,
 located within a single directory, into a blog consisting of static
 HTML files.

  This importer script will create a directory of input files from a
 given RSS feed, by downloading it and writing out each entry to a single
 text file.

  The output files will be named after the entries titles, or if
 B<--sequential> was used each entry will be numbered numerically.
