 Let's WikifyGoogleSidewiki with some additional GroovyCode?.
 What about a '''really''' GroovyGoogleSidewiki?

 This text serves for testing this GroovySnippet? which transforms a text
 with some typical WikiSyntax, that is not yet supported by Google's
 SideWiki:
 * CamelCase
 * ''ItalicizedText''
 * ''' ''BoldItalicizedText'' ''' (containing '''Camel ''case'' or not''' )
 * BracketLinks such as: [http://www.usemod.com/cgi-bin/mb.pl?WikifyGoogleSidewiki WikifyGoogleSidewiki]
 * Bold BracketLinks such as:''' [http://www.usemod.com/cgi-bin/mb.pl?WikifyGoogleSidewiki WikifyGoogleSidewiki] ''' 
 * GoogleTagLinks? like this Tag+Tic+ Toc+
