Thanks to frew++, Catalyst-Manual is now no longer on svn and has moved to shadowcat's git hosting. You can get a copy of the manual with the tutorial attached.
Grab a fork with:
git clone firstname.lastname@example.org:Catalyst-Manual
If you have patches, please contact this list with patches, or join #catalyst-dev on irc.perl.org for further instructions.
If this is not practical for you you can also grab a copy from http://search.cpan.org/perldoc?Catalyst::Manual then it's a mater of downloading and untarring the source, then:
$ git init
$ git add *
$ git commit -m 'initial import'
# time passes ... stuff gets edited
$ git diff > patch.diff
and send the patch.diff file to this list or talk to us on IRC as above (IRC is preferred in general).
