How to use debug mode

[nickh]

G'day folks. I'm writing my first plugin/product, and am trying to figure out how to use vBulletin's "debug mode".

After enabling it, the only things I see are:
1) A tiny bit of database output at the bottom of each admin page;
2) A table of debug information at the bottom of each public page.

How does one get debug messages to be displayed somewhere on vBulletin pages, or should I simply write those debug messages to a file?

Thanks,
Nick
