+"""BulletML parser.
+
+BulletML is the Bullet Markup Language. BulletML can describe the
+barrage of bullets in shooting games. (For example Progear, Psyvariar,
+Gigawing2, G DARIUS, XEVIOUS, ...) This module parses and executes
+BulletML scripts in Python. All data structures in it are
+renderer-agnostic.
+
+In addition to the standard BulletML XML format, this module supports
+an equivalent YAML format. See bulletml.bulletyaml for more details.
+
+More information is available at the BulletML homepage,
+http://www.asahi-net.or.jp/~cs8k-cyu/bulletml/index_e.html, or the
+python-bullet homepage, http://code.google.com/p/python-bulletml/.
+
+Basic Usage:
+
+    from bulletml import Bullet, BulletML
+    doc = Bulletml.BulletML.FromDocument(open("test.xml", "rU"))
+    rank = 0.5    # Player difficulty, 0 to 1
+    params = []   # Initial variable settings, usually empty
+    actions = [a(params, rank) for a in doc.top]
+    bullet = Bullet(x, y, target=player, actions=actions, rank=rank)
+    bullets = [bullet]
+    ...
+    for bullet in bullets:
+        bullets.extend(bullet.step())
+
+    ...
+
+For drawing, you're on your own, but Bullet instances have a number of
+attributes that can be used to influence it.
