I’m a twentysomething coder living la vida loca on the southern coast of Spain. I work primarily with Ruby on Rails and Drupal, and dabble in the dark art of Lisp programming for my own amusement.
Lisp is worth learning for the profound enlightenment experience you will have when you finally get it; that experience will make you a better programmer for the rest of your days, even if you never actually use Lisp itself a lot.
— Eric Raymond, “How to Become a Hacker”
This is great.
Yes, integration with devel would be nice.
Another thing, for the debug, make that a hook that modules can use, so they can output things they want to see, instead of print_r(), var_dump(), ...etc.
Also make it more granular, with an easy interface, for example: What to log in one field group with check marks on what to enable/disable.
Another thing that may be useful in the README is the variable names that you use to enable these stuff. Would be nice to have them so one can stick his pre-set variables in $conf on a test site quickly (using a simple cat command or something). Also candidate for the to-be-developed drush script.
