Re: [Jsynthlib-devel] Got something going but...

[Daniel R. <dr....@co...>]

Hi Michael,

1) three hours of tinkering is either not mentioned or called, "a bit of
tinkering" when you develop software. Plan to lose many more.
2) I did give up on JSynthLib (resulting in www.confusionists.com/handsonic),
but there was a LOT of help on the list. I ditched it because what I needed
to do was not really a librarian.
3) My guess: it's August, they're Europeans, and so you have to wait until
September when they are actually working.
4) Sounds like your problems are outside of JSynthlib anyway, but I'm not
sure. Use JSynthlib if you are going to be making that kind of functionality
anyway.

good luck!
