Checkbot is a tool to verify links on a set of HTML pages. Checkbot can check a single document, or a set of documents on one or more servers. Checkbot creates a report which summarizes all links which caused some kind of warning or error.

Checkbot requires the following additional software, all of which is also available at CPAN. Try running the 'cpan' command to install them in your perl installation.

In general, it is recommended to always use the most recent version of these modules.


I usually keep an example of a Checkbot run around.
