+ * `rss-bridge-twitter.php` : Twitter. Parameters:
+ * q=keyword : Keyword search.
+ * u=username : Get user timeline.
+Output format
+===
+Output format can be used in any rss-bridge:
+
+ * `format=atom` (default): ATOM Feed.
+ * `format=json` : jSon
+ * `format=html` : html page
+ * `format=plaintext` : raw text (php object, as returned by print_r)
+
+If format is not specified, ATOM format will be used.
+
+Examples
+===
+ * `rss-bridge-twitter.php?u=Dinnerbone` : Get Dinnerbone (Minecraft developer) timeline, in ATOM format.
+ * `rss-bridge-twitter.php?q=minecraft&format=html` : Everything Minecraft from Twitter, in html format.
+ * `rss-bridge-flickr-explore.php` : Latest interesting images from Flickr, in ATOM format.

+
+Technical notes
+===
+ * There is a cache so that source services won't ban you even if you hammer the rss-bridge with requests. Each bridge has a different duration for the cache. The `cache` subdirectory will be automatically created. You can purge it whenever you want.
+ * To implement a new rss-bridge, import `rss-bridge-lib.php` and subclass `RssBridgeAbstractClass`. Look at existing bridges for examples. For items you generate in `$this->items`, only `uri` and `title` are mandatory in each item. `timestamp` and `content` are optional but recommended. Any additional key will be ignored by ATOM feed (but outputed to jSon).
