"""
Extension functions for easier form filling.

(This module is a dumping ground for features that may ultimately get
added into the main twill command set.)

Commands:

 * fv_match -- fill in *all* fields that match a regexp (unlike 'formvalue'
        which will complain about multiple matches).  Useful for forms
        with lots of repeated fieldnames -- 'field-1', 'field-2', etc.

 * fv_multi -- fill in multiple form fields at once, e.g.

          fv_multi <formname> field1=value1 field2=value2 field3=value3

 * fv_multi_sub -- same as 'fv_multi', followed by a 'submit'.
