Hi Larry

Sorry if this is a silly question but I haven't been able to find the
answer. Is the perl6-synopsis SVN repository publicly available or is it
in the same repository as that of Parrot or Pugs?

Thanks in advance
Blair

The versions that appear on dev.perl.org are available from
http://svn.perl.org/perl6/doc/trunk/design/syn/ .

There are also some draft synopses available from
http://svn.pugscode.org/pugs/docs/Perl6/Spec/ .

Hope this helps!

Pm
