[Trac] creating new reports

[Edward Q. Bridges]

Granted this is probably a pretty boneheaded question . . . the answer is
probably staring me in the face somewhere.

I've perfectly fine with how to craft a report -- i.e. I make a SQL query
and all that.

Where and how do I actually enter the SQL query into Trac so that it's
available to use?

Have looked in:
http://projects.edgewall.com/trac/wiki/TracReports
and sundry other places

Please advise,

thanks
Ed
