gPal's PayPal interface library is based in no small part on ppsend
0.3 by hampa <hampa@chello.se>. If you fancy a simple command line
utility to send money with PayPal, check out ppsend at

Thanks to Paul Ashton and Tommy Holmes for risking their hard-earned
cash testing early versions of gPal :-)
