Terms and Conditions:

P-Moontool uses MathLib.
MathLib is free Software and distributed under the terms of the GNU Lesser General Public License (LGPL)

You may freely copy and distribute P-Moontool, as long as You also provide the source code.
(the source code to both P-Moontool and MathLib can be downloaded from the Project Homepage resp. MathLib's Homepage)

I make two exceptions to this rule:

  • Beaming P-Moontool from one PalmOS Device to another is allowed
    (without handing over a discette with the source ;-) )
  • Download ONLY the binary package from the Project's homepage or a mirror site for personal use is allowed.

That means if You plan to distribute P-Moontool (for instance on CD-ROM, or on some WEB-Site) You may NOT just distribute the binary package, but You also have to distribute the source code packages of both P-Moontool and MathLib.
