1 <!DOCTYPE html><!-- This page is a placeholder for generated extensions api doc. Note:
2 1) The <head> information in this page is significant, should be uniform
3 across api docs and should be edited only with knowledge of the
4 templating mechanism.
5 3) All <body>.innerHTML is genereated as an rendering step. If viewed in a
6 browser, it will be re-generated from the template, json schema and
7 authored overview content.
8 4) The <body>.innerHTML is also generated by an offline step so that this
9 page may easily be indexed by search engines.
