# PHPTAL Licence

PHPTAL is licensed under [LGPL](http://www.gnu.org/licenses/lgpl-2.1.html) (v2.1 or later).

## Use in commercial projects

The licence does not 'infect' other software you use with PHPTAL, so it's safe for commercial (closed, for-profit) use in PHP applications.

-  You **can** use it in commercial applications.

-  Your website and your templates **remain your property** and are unaffected by the license.

-  You **can** redistribute PHPTAL with applications, even if they're not free/open-source.

-  You **can** charge money for PHPTAL customisations and you can even [sell modified versions of PHPTAL](http://www.gnu.org/philosophy/selling.html) (although you cannot forbid redistribution).

## Your obligations

**You only have obligations if you *redistribute* PHPTAL** (give PHPTAL's source code to others). Sending of PHPTAL-generated HTML from a server doesn't count as redistribution.

-  If you *modify and redistribute* PHPTAL, then your modifications of PHPTAL's code (and only PHPTAL's code) become LGPL-licensed.  
However, if you always keep PHPTAL only on your server, then you're allowed to keep your modifications secret.

-  If you redistribute your application to others with PHPTAL built-in, it must be possible to modify PHPTAL part of the application. If you use copy protection (encryption/obfuscation of PHP files), don't apply it to PHPTAL files.

-  Don't remove license (`COPYING` file) from PHPTAL copies you give to others.
