This handy module allowed me to more easily find a bug in my code. Being able to see variable values as it traces each line of code is immensely helpful. It was easy to start using, and the documentation is clear. Another great feature is the ability to control whether it traces through module (package) code.
If you want to get a glimpse of what your POD will look like on CPAN before you upload your module to CPAN, then this is for you. It is as close as you're going to get to the real thing. It is an essential tool for developing CPAN modules.
The command-line utility script is a great convenience because it is so simple to use.
This module suits my needs perfectly. I use it on simple XML files to isolate my actual content changes from all the unnecessary attribute re-ordering imposed by an XML writer tool I am forced to use. The distribution includes a simple script which works right out of the box.
Furthermore, the current maintainer, Shlomi Fish, fixed a minor POD error within hours of my request!
