Perl Tablets: Revision 15
Yes, these are the Perl Tablets, the english version of the german, nicely linked Perl 6 Overview. The first attempt was started down under, but let's make it more official here. If you need a sleazy intro, try the Perl 6 Tutorial.
DISCLAIMER: completely translated are currently only the introduction and the 5 appendices.
