hej

Fine piece of software.

But your licence is absolute useless not to say flawed:

  "Permission granted to use this library, without any warranty, for any
   purpose, provided this copyright note remains attached and modified".

When you get hold of a pice of software in a legal manner (in this case
by downloading from your site). You are allways allowed to use it
in any way you see fit, as long as you dont copy it or puplicise it.

So this note dosn't grant any new rigths at all to the user. On the 
conterary you are actualy trying too put limitations on the use (witch 
you have no legal base to do) by  requiring him to keep the the 
copyrigth notice, a litle bit odd since you are not granting him rigth 
to copy :-)

If you want your libery to be used in any larger scale i recomend you to
use one of the well-known licences as BSD or GPL or LGPL . BSD or LGPL 
will probley give you the most user since a pure GPL will restrict the 
use to ather GPL-programs.
