 python-bulletml - BulletML for Python
 -------------------------------------
 
-This module parses and runs BulletML scripts. BulletML is a markup
-language for describing complex bullet patterns in shooting games.
-More information is available at the BulletML homepage,
-http://www.asahi-net.or.jp/~cs8k-cyu/bulletml/index_e.html.
+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.
 
-The module code is renderer-agnostic. A sample renderer for Pygame is
-included.
+Finally, two simple collision routines are provided, bulletml.overlaps
+for stationary circles and bulletml.collides for moving circles.
+
+A sample renderer for Pygame is included.

+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/.

+Use Page Up and Page Down to switch between bullet definitions, S to
+respawn the bullet pattern, and Enter to restart it.
 
 
 Installing
 ----------
+BulletML requires Python 2.6 or later. It should work on Python 3. It
+has no dependencies outside the CPython standard library.
