Description: There are two scripts here, and a sample crontab. gets & stores daily cookbook recipes from Written to run as a cronjob (no output except the file) & includes a sample daily crontab to automate the process. lists the saved recipes in alphabetical order. The viewer requires two images to work properly, 1. a small transparent gif named blank.gif, and 2. a Perl Cookbook cover image such as these at fatbrain and amazon, both stored in the same dir as the scripts & saved files.

Update: fixed url to point to the new recipe location at
