freshmeat Project Query Class queries freshmeat.net and retrieves information on projects with records there. It features retrieval of project information from records provided by freshmeat in XML, parsing of project XML records to extract all the relevant data, and caching of retrieved project information in disk files for at least the next day to avoid retrieving the same data again before it could have been updated.
c_xml is a class that can convert between XML files and arrays or strings. It can parse an XML file into a DOM document object, so it can be returned as an array or displayed using a XSL stylesheet.

SMTP client class is a PHP class that connects to a mail server to send messages.
