[php-maint] Is the XDebug License Ok?

[Mark A. Hershberger]

I have a package for php-xdebug (Bug #37734) and just wanted to verify
that the license is ok.  http://xdebug.org/license.php

It looks like a variant of the PHP license with XDebug specifically
mentioned in the place of PHP.  From my understanding of the problems of
applying the PHP license to packages that aren't included in PHP is that
the license is written such that it only covers things included with
PHP.

I realize I should ask this on debian-legal, but wanted to check here.

Also, I wanted to make sure I understood the process for adding a new
package to the subversion repository: I should be able to just create
the appropriate subdirectory, right?
