THANKS

299       This tutorial would not have been possible without the input of many
300       different people in the Catalyst community.  In particular, the primary
301       author would like to thank:
302
303       ·   Sebastian Riedel for founding the Catalyst project.
304
305       ·   The members of the Catalyst Core Team for their tireless efforts to
306           advance the Catalyst project.  Although all of the Core Team
307           members have played a key role in this tutorial, it would have
308           never been possible without the critical contributions of: Matt
309           Trout, for his unfathomable knowledge of all things Perl and
310           Catalyst (and his willingness to answer lots of my questions);
311           Jesse Sheidlower, for his incredible skill with the written word
312           and dedication to improving the Catalyst documentation; and Yuval
313           Kogman, for his work on the Catalyst "Auth & Authz" plugins (the
314           original focus of the tutorial) and other key Catalyst modules.
315
316       ·   Other Catalyst documentation folks like Kieren Diment, Gavin Henry,
317           and Jess Robinson (including their work on the original Catalyst
318           tutorial).
319
320       ·   Kieren Diment for his oversight of Catalyst-related documentation.
321
322       ·   Everyone on #catalyst and #catalyst-dev.
323
324       ·   Louis Moore (who thanks Marcello Romani and Tom Lanyon) for the
325           PostgreSQL content in the Appendix.
326
327       ·   People who have emailed me with corrections and suggestions on the
328           tutorial. As of the most recent release, this include: Florian
329           Ragwitz, Mauro Andreolini, Jim Howard, Giovanni Gigante, William
330           Moreno, Bryan Roach, Ashley Berlin, David Kamholz, Kevin Old,
331           Henning Sprang, Jeremy Jones, David Kurtz, Ingo Wichmann, Shlomi
332           Fish, Murray Walker, Adam Witney and xenoterracide (Caleb Cushing).
333           Thanks to Devin Austin for coming up with an initial version of a
334           non-TTSite wrapper page. Also, a huge thank you to Kiffin Gish for
335           all the hard work on the "database depluralization" effort and
336           Rafael Kitover for the work on updating the tutorial to include
337           foreign key support for SQLite. I'm sure I am missing some names
338           here... apologies for that (please let me know if you name should
339           be here).
