=head1 ABOUT

  chronicle-spooler is a companion scrip to the chronicle blog compiler.

  It is designed to facilitate posting new entries automatically upon
 particular dates.  (ie. If you have ten written blog entries in a spool
 directory it will move them into place upon the date you've specified.)

=cut


=head1 DATE SPECIFICATION

  To specify the date a particular entry should be made live you
 must add another pseudo-header to your blog entry files, as follows:

=for example begin

    Title:  This is the title of the blog post
    Date:  2nd March 2007
    Publish: 15th April 2008
    Tags: one, two, three, long tag

    The text of your entry goes here.

=for example end

  In this example we know that this entry will be made live upon the
 15th April 2008, and not before.
