The fonts and derivatives, however, cannot be released under any other type of license. The requirement for fonts to remain under this license does not apply to any document created using the fonts or their derivatives.

+// showdown.js -- A javascript port of Markdown.
+//
+// Copyright (c) 2007 John Fraser.
+//

+//   <http://daringfireball.net/projects/markdown/>
+//

+//
+//
+// 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 converter = new Showdown.converter();
+//   var html = converter.makeHtml(text);
+//
+//   alert(html);
+//
+// Note: move the sample code to the bottom of this
+// file before uncommenting it.

The fonts and derivatives, however, cannot be released under any other type of license. The requirement for fonts to remain under this license does not apply to any document created using the fonts or their derivatives.

+// showdown.js -- A javascript port of Markdown.
+//
+// Copyright (c) 2007 John Fraser.
+//

+//   <http://daringfireball.net/projects/markdown/>
+//

+//
+//
+// 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 converter = new Showdown.converter();
+//   var html = converter.makeHtml(text);
+//
+//   alert(html);
+//
+// Note: move the sample code to the bottom of this
+// file before uncommenting it.

+// showdown.js -- A javascript port of Markdown.
+//
+// Copyright (c) 2007 John Fraser.
+//
+// Original Markdown Copyright (c) 2004-2005 John Gruber
+//   <http://daringfireball.net/projects/markdown/>
+//

+//
+//
+// 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 converter = new Showdown.converter();
+//   var html = converter.makeHtml(text);
+//
+//   alert(html);
+//
+// Note: move the sample code to the bottom of this
+// file before uncommenting it.

+SIL OPEN FONT LICENSE Version 1.1 - 26 February 2007
+—————————————————————————————-
+
+PREAMBLE
+The goals of the Open Font License (OFL) are to stimulate worldwide development of collaborative font projects, to support the font creation efforts of academic and linguistic communities, and to provide a free and open framework in which fonts may be shared and improved in partnership with others.
+
+The OFL allows the licensed fonts to be used, studied, modified and redistributed freely as long as they are not sold by themselves. The fonts, including any derivative works, can be bundled, embedded, redistributed and/or sold with any software provided that any reserved names are not used by derivative works. The fonts and derivatives, however, cannot be released under any other type of license. The requirement for fonts to remain under this license does not apply to any document created using the fonts or their derivatives.
+

+
+“Reserved Font Name” refers to any names specified as such after the copyright statement(s).
+
+“Original Version” refers to the collection of Font Software components as distributed by the Copyright Holder(s).
+

+
+3) No Modified Version of the Font Software may use the Reserved Font Name(s) unless explicit written permission is granted by the corresponding Copyright Holder. This restriction only applies to the primary font name as presented to the users.
+
+4) The name(s) of the Copyright Holder(s) or the Author(s) of the Font Software shall not be used to promote, endorse or advertise any Modified Version, except to acknowledge the contribution(s) of the Copyright Holder(s) and the Author(s) or with their explicit written permission.
+
+5) The Font Software, modified or unmodified, in part or in whole, must be distributed entirely under this license, and must not be distributed under any other license. The requirement for fonts to remain under this license does not apply to any document created using the Font Software.

+// 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 converter = new Showdown.converter();
+//   var html = converter.makeHtml(text);
+//
+//   alert(html);
+//
+// Note: move the sample code to the bottom of this
+// file before uncommenting it.
