Re: [development] Modules that integrate non-GPL PHP apps violate the GPL.

Quoting Jeff Eaton <jeff@viapositiva.net>:

*** If you can, at any point, call debug_backtrace() and see BOTH drupal functions AND functions from a non-GPL-compatible piece of software, the terms of the GPL are being violated. ***

Then any project that uses PHP and claims to be GPL is violating the terms of the GPL as a rule of thumb. PHP isn't GPL licensed[1] and its functions are viewable in a debug_backtrace(). [1] http://www.php.net/license/3_01.txt Earnie
