// this is the php file which creates the readme.pdf file, this is not seriously
// suggested as a good way to create such a file, nor a great example of prose,
// but hopefully it will be useful
//
// adding ?d=1 to the url calling this will cause the pdf code itself to be echoed to the
// browser, this is quite useful for debugging purposes.
// there is no option to save directly to a file here, but this would be trivial to implement.
//
// note that this file comprises both the demo code, and the generator of the pdf documentation
//
//===================================================================================================
// don't want any warnings turning up in the pdf code if the server is set to 'anal' mode.
