-// 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.
