45 <p> <i>Welcome to zcommit.</i> </p>
47 <p> zcommit allows you to send zephyr notifications by sending an HTTP
48 POST request to a URL. Currently zcommit supports POST-backs from
49 github. If you would like it to support another form of POST-back,
50 please let us know (zcommit@mit.edu). </p>
52 <h1> URL structure </h1>
54 The URL you post to is structured as follows:
55 <tt>http://zcommit.mit.edu/$type/$key1/$value1/$key2/$value2/...</tt>.
56 So for example, the URL
57 <tt>http://zcommit.mit.edu/github/class/zcommit/instance/commit</tt>
58 is parsed as having type <tt>github</tt>, class <tt>zcommit</tt>, and
59 instance <tt>commit</tt>. Using this information, zcommit figures out
60 how to form a useful message which is then sends as a zephyr.
64 Set your POST-back URL to
65 <tt>http://zcommit.mit.edu/github/class/$classname</tt>, followed by
66 any of the following optional key/value parameters:
69 <li> <tt>/instance/$instance</tt> </li>
70 <li> <tt>/zsig/$zsig</tt> </li>
71 <li> <tt>/sender/$sender</tt> </li>
