Re: [Dltk-dev] Dynamic handling of DLTK contributors

[William Candillon <wcandillon@xxxxxxxxx>]

Hello,

I documented a small example of extending DLTK in a dynamic manner.
This works only with the patch I submitted:
http://code.google.com/p/jspde/wiki/ExampleOfDynamicPlugin
I'm looking forward to receive your comments on this.

Best regards,

William
