specify bbox in query

[wendellwt]

I want to specify one bounding box when specifying a query, not on each line. Neither 'build' option seemed to work (true/false), because both TEMPLATE variables began with '[out:whatever];', and from what I understand about OverpassQL, the bounding box must appear before the first ';'.

I edited api.py to insert an optional bbox spec in the template. The 'git diff' is attached.
