+//
+
+//
+// Wherever possible, Showdown is a straight, line-by-line port
+// of the Perl version of Markdown.
+//
+// This is not a normal parser design; it's basically just a
+// series of string substitutions. It's hard to read and
+// maintain this way, but keeping Showdown close to the original
+// design makes it easier to port new features.
+//
+// More importantly, Showdown behaves like markdown.pl in most
+// edge cases. So web applications can do client-side preview
+// in Javascript, and then build identical HTML on the server.
+//
+// This port needs the new RegExp functionality of ECMA 262,
+// 3rd Edition (i.e. Javascript 1.5). Most modern web browsers
+// should do fine. Even with the new regular expression features,
+// We do a lot of work to emulate Perl's regex functionality.
+// The tricky changes in this file mostly have the "attacklab:"
+// label. Major or self-explanatory changes don't.
+//
+// Smart diff tools like Araxis Merge will be able to match up
+// this file with markdown.pl in a useful way. A little tweaking
+// helps: in a copy of markdown.pl, replace "#" with "//" and
+// replace "$text" with "text". Be sure to ignore whitespace
+// and line endings.
+//
+
+
+//
+// Showdown usage:
+//
+// var text = "Markdown *rocks*.";
+//
+// var markdown = require("markdown");
+// var html = markdown.encode(text);
+//
+// print(html);
+//
+// Note: move the sample code to the bottom of this
+// file before uncommenting it.
