AW: GnuPG with PHP

Yes, according to the info available at:  http://www.php.net/license/
PHP had a dual license: one of them was GPL; and PHP4 hasn't any
longer the GPL license.

Well, in that same page, it is written that:

" (...) Essentially, the PHP license gives you the right to use,
distribute and modify PHP as much as you want, for both commercial and
non-commercial use. You just have to make it clear to the user that
what you have distributed contains PHP.  (...) You are free to
distribute PHP source code you write freely or commercially, without
any concern about the PHP or Zend licenses. (...) You may also package
PHP as a whole with your commercial applications as much as you want.
You just can't build commercial applications that use the Zend
scriping engine library directly."

And then it goes like this:

"[1] You should be aware of the Zend license in two cases. First, if
you publish patches to the Zend scriping engine library. The Zend
license allows Zend Technologies, Ltd. to use those patches
royalty-free (see the license for exact details)".
"[2] Second, the license prevents commercial use of the Zend scriping
engine library to build commercial applications. "

I think these two are acceptable for gnuPG, since gnuPG is
non-commercial software. Am I right?  This is NOT intended as a flame:
I am just trying to gain some understanding of the reasons that avoid
gnuPG to link code to PHP4.


By the way, I am _not_ affiliated with PHP / Zend / gnuPG /whatever...
I am just a happy developer of PHP scripts (_not_ PHP source code
itself, possibly written in C) and I also am a happy user of gnuPG  :)
