It's a CPAN module. I'm using it for exception handling in  
DB::Schema::NewSQL.

By the way, the latest versions of DB.pm probably don't work that  
well with the original Schema::SQL and Schema::Moodle::* modules...  
I've made several changes for NewSQL that probably don't play nice  
with the older stuff.

If you're going to use the latest DB stuff, you should probably  
switch over to using NewSQL. If you don't want to bother with it, you  
can back out of the last couple of weeks' worth of changes to lib/ 
WeBWorK/DB.pm and lib/WeBWorK/DB/* without problems.

Here's my database.conf that uses NewSQL, NewSQL::Merged, etc. The  
moodle stuff isn't done, so I wouldn't use that yet. I should be done  
with this stuff by the end of the week.
