[PEPr] Comment on XMPP::JAXL

I opened a "pearified" branch of my jaxl fork on github. It should serve as example how to do it, and could server as starting point for you to get jaxl prepared for PEAR: https://github.com/cweiske/JAXL/tree/pearified Please have a look at it. - the compat directory is not full yet, I only added some examples so you can see how it could look like - I would split the package up into two packages: Net_XMPP and Net_XMPP_Client. Net_XMPP only implements the xmpp protocol details, while Net_XMPP_Client contains all the files that assists you in creating the client. Some things I saw when looking through the source code: - Log -> replace with Log package - no static logging, always use configured instance - util -> replace curl() with http_request2 usage - XEP classes without leading zeros, since 4 zeros may not be enough in the future - get rid of jaxl_require - replace define() with class constants - rename jaxl in the files to net_xmpp - follow pear coding standards, run phpcs on it - php5: public/private/protected instead of "var" - use type hints in method parameters - get rid of JAXL_BASE_PATH and jaxl_instance_count - no global constants, no global variables allowed! - I only fixed the file names and the "class $classname" declarations. I did not test them, and did not rename class usages - this is left to do - there are absolutely no unit tests, which is a shame for such a big bag of source code - docblocks everywhere are missing. very important is the description of array keys that are required in the parameter arrays, i.e. in Net_XMPP_Get - return values are also not documented - parts of Net_XMPP_Client_Util probably can be replaced by using pear packages, i.e. isWin() is available in the PEAR System class, hmacMD5 is in the PEAR Crypt_HMAC package -- http://pear.php.net/pepr/pepr-proposal-show.php?id=635
