This script, named build-tree.php, will connect to the CouchDB
instance and dump out the tree of all configured databases on the
system. This is useful during script development to be able to
get a full list of the internal field identifiers for use with
getFieldValue and similar commands. Assuming you have the basic
configuration set up, you can run ./build-tree.php to get a
listing of all documents, forms and their fields.
