-comment(# == What is Rweb?)
-comment(# Rweb is a replacement for the cgi class included in the ruby distribution.)
-comment(#)
-comment(# == How to use)
-comment(#)
-comment(# === Basics)
-comment(#)
-comment(# This class is made to be as easy as possible to use. An example:)
-comment(#)
-comment(# 	require "rweb")
-comment(#)
-comment(# 	web = Rweb.new)
-comment(# 	web.out do)
-comment(# 		web.puts "Hello world!")
-comment(# 	end)
-comment(#)
-comment(# The visitor will get a simple "Hello World!" in his browser. Please notice,)
-comment(# that won't set html-tags for you, so you should better do something like this:)
-comment(#)
-comment(# 	require "rweb")
-comment(#)
-comment(# 	web = Rweb.new)
-comment(# 	web.out do)
-comment(# 		web.puts "<html><body>Hello world!</body></html>")
-comment(# 	end)
-comment(#)
-comment(# === Set headers)
-comment(# Of course, it's also possible to tell the browser, that the content of this)
-comment(# page is plain text instead of html code:)
-comment(#)
-comment(# 	require "rweb")
-comment(#)
-comment(# 	web = Rweb.new)
-comment(# 	web.out do)
-comment(# 		web.header("content-type: text/plain"\))
-comment(# 		web.puts "Hello plain world!")
-comment(# 	end)
-comment(#)
-comment(# Please remember, headers can't be set after the page content has been send.)
-comment(# You have to set all nessessary headers before the first puts oder print. It's)
-comment(# possible to cache the content until everything is complete. Doing it this)
-comment(# way, you can set headers everywhere.)
-comment(#)
-comment(# If you set a header twice, the second header will replace the first one. The)
-comment(# header name is not casesensitive, it will allways converted in to the)
-comment(# capitalised form suggested by the w3c (http://w3.org\))
-comment(#)
-comment(# === Set cookies)
-comment(# Setting cookies is quite easy:)
-comment(# 	include 'rweb')
-comment(#)
-comment(# 	web = Rweb.new)
-comment(# 	Cookie.new("Visits", web.cookies['visits'].to_i +1\))
-comment(# 	web.out do)
-comment(# 		web.puts "Welcome back! You visited this page #{web.cookies['visits'].to_i +1} times")
-comment(# 	end)
-comment(#)
-comment(# See the class Cookie for more details.)
-comment(#)
-comment(# === Get form and cookie values)
-comment(# There are four ways to submit data from the browser to the server and your)
-comment(# ruby script: via GET, POST, cookies and file upload. Rweb doesn't support)
-comment(# file upload by now.)
-comment(#)
-comment(# 	include 'rweb')
-comment(#)
-comment(# 	web = Rweb.new)
-comment(# 	web.out do)
-comment(# 		web.print "action: #{web.get['action']} ")
-comment(# 		web.puts "The value of the cookie 'visits' is #{web.cookies['visits']}")
-comment(# 		web.puts "The post parameter 'test['x']' is #{web.post['test']['x']}")
-comment(# 	end)

-
-	WHAT IS A TAG?
-	==============
-
-	Tags in BBCode can be much more than just a simple [b].
-	I use many terms here to differ the parts of each tag.
-
-	Basic scheme:
-	    [         code        ]
-	TAG START   TAG INFO   TAG END
-
-	Most tags need a second tag to close the range it opened.
-	This is done with CLOSING TAGS:
-		[/code]
-	or by using empty tags that have no content and close themselfes:
-		[url=winamp.com /]
-	You surely know this from HTML.
-	These slashes define the TAG KIND = normal|closing|empty and
-	cannot be	used together.
-
-	Everything between [ and ] and expluding the slashes is called the
-	TAG INFO.	This info may contain:
-	- TAG ID
-	- TAG NAME including the tag id
-	- attributes
-
-	The TAG ID is the first char of the info:
-
-	TAG       | ID
-	----------+----
-	[quote]   | q
-	[&plusmn] | &
-	["[b]"]   | "
-	[/url]    | u
-	[---]     | -
-
-	As you can see, the tag id shows the TAG TYPE, it can be a
-	normal tag,	a formatting tag or an entity.
-	Therefor, the parser first scans the id to decide how to go
-	on with parsing.

+comment(# == What is Rweb?)
+comment(# Rweb is a replacement for the cgi class included in the ruby distribution.)
+comment(#)
+comment(# == How to use)
+comment(#)
+comment(# === Basics)
+comment(#)
+comment(# This class is made to be as easy as possible to use. An example:)
+comment(#)
+comment(# 	require "rweb")
+comment(#)
+comment(# 	web = Rweb.new)
+comment(# 	web.out do)
+comment(# 		web.puts "Hello world!")
+comment(# 	end)
+comment(#)
+comment(# The visitor will get a simple "Hello World!" in his browser. Please notice,)
+comment(# that won't set html-tags for you, so you should better do something like this:)
+comment(#)
+comment(# 	require "rweb")
+comment(#)
+comment(# 	web = Rweb.new)
+comment(# 	web.out do)
+comment(# 		web.puts "<html><body>Hello world!</body></html>")
+comment(# 	end)
+comment(#)
+comment(# === Set headers)
+comment(# Of course, it's also possible to tell the browser, that the content of this)
+comment(# page is plain text instead of html code:)
+comment(#)
+comment(# 	require "rweb")
+comment(#)
+comment(# 	web = Rweb.new)
+comment(# 	web.out do)
+comment(# 		web.header("content-type: text/plain"\))
+comment(# 		web.puts "Hello plain world!")
+comment(# 	end)
+comment(#)
+comment(# Please remember, headers can't be set after the page content has been send.)
+comment(# You have to set all nessessary headers before the first puts oder print. It's)
+comment(# possible to cache the content until everything is complete. Doing it this)
+comment(# way, you can set headers everywhere.)
+comment(#)
+comment(# If you set a header twice, the second header will replace the first one. The)
+comment(# header name is not casesensitive, it will allways converted in to the)
+comment(# capitalised form suggested by the w3c (http://w3.org\))
+comment(#)
+comment(# === Set cookies)
+comment(# Setting cookies is quite easy:)
+comment(# 	include 'rweb')
+comment(#)
+comment(# 	web = Rweb.new)
+comment(# 	Cookie.new("Visits", web.cookies['visits'].to_i +1\))
+comment(# 	web.out do)
+comment(# 		web.puts "Welcome back! You visited this page #{web.cookies['visits'].to_i +1} times")
+comment(# 	end)
+comment(#)
+comment(# See the class Cookie for more details.)
+comment(#)
+comment(# === Get form and cookie values)
+comment(# There are four ways to submit data from the browser to the server and your)
+comment(# ruby script: via GET, POST, cookies and file upload. Rweb doesn't support)
+comment(# file upload by now.)
+comment(#)
+comment(# 	include 'rweb')
+comment(#)
+comment(# 	web = Rweb.new)
+comment(# 	web.out do)
+comment(# 		web.print "action: #{web.get['action']} ")
+comment(# 		web.puts "The value of the cookie 'visits' is #{web.cookies['visits']}")
+comment(# 		web.puts "The post parameter 'test['x']' is #{web.post['test']['x']}")
+comment(# 	end)
+

+comment(=begin
+
+	WHAT IS A TAG?
+	==============
+
+	Tags in BBCode can be much more than just a simple [b].
+	I use many terms here to differ the parts of each tag.
+
+	Basic scheme:
+	    [         code        ]
+	TAG START   TAG INFO   TAG END
+
+	Most tags need a second tag to close the range it opened.
+	This is done with CLOSING TAGS:
+		[/code]
+	or by using empty tags that have no content and close themselfes:
+		[url=winamp.com /]
+	You surely know this from HTML.
+	These slashes define the TAG KIND = normal|closing|empty and
+	cannot be	used together.
+
+	Everything between [ and ] and expluding the slashes is called the
+	TAG INFO.	This info may contain:
+	- TAG ID
+	- TAG NAME including the tag id
+	- attributes
+
+	The TAG ID is the first char of the info:
+
+	TAG       | ID
+	----------+----
+	[quote]   | q
+	[&plusmn] | &
+	["[b]"]   | "
+	[/url]    | u
+	[---]     | -
+
+	As you can see, the tag id shows the TAG TYPE, it can be a
+	normal tag,	a formatting tag or an entity.
+	Therefor, the parser first scans the id to decide how to go
+	on with parsing.
