License
All libraries are released under the LGPL, the Lesser Gnu Public License. It is not the intention to be in any way religous about the license. Basically any license is suitable as long as it
- allows the functions to be used in whatever application, including closed source applications
- allows free modification and distribution of the functions.
- requires the license to be included when distributing the functions. In such a case, the license is required to apply to the UDF's - it is not required to extend to the remainder of the product.
