<h1>License</h1> |
|
|
|
The source for the Shapefile C Library is (c) 1998 Frank Warmerdam, |
|
and released under the following conditions. The intent is that anyone |
|
can do anything with the code, but that I do not assume any liability, nor |
|
express any warranty for this code. <p> |
|
|
|
As of Shapelib 1.2.6 the core portions of the library are made available |
|
under two possible licenses. The licensee can choose to use the code |
|
under either the Library GNU Public License (LGPL) described in |
|
COPYING or under the following MIT style license. Any files in |
|
the Shapelib distribution without explicit copyright license terms |
|
(such as this documentation, the Makefile and so forth) should be |
|
considered to have the following licensing terms. Some auxilary portions |
|
of Shapelib, notably some of the components in the contrib directory |
|
come under slightly different license restrictions. Check the source |
|
files that you are actually using for conditions.<p> |

Copyright (c) 1999, Frank Warmerdam<p> |

This software is available under the following "MIT Style" license, |
|
or at the option of the licensee under the LGPL (see COPYING). This |
|
option is discussed in more detail in shapelib.html.<p> |

<h3>Shapelib Modifications</h3> |
|
|
|
I am pleased to receive bug fixes, and improvements for Shapelib. Unless |
|
the submissions indicate otherwise I will assume that changes submitted to |
|
me remain under the the above "dual license" terms. If changes are made |
|
to the library with the intention that those changes should be protected by |
|
the LGPL then I should be informed upon submission. Note that I will not |
|
generally incorporate changes into the core of Shapelib that are protected |
|
under the LGPL as this would effectively limit the whole file and |
|
distribution to LGPL terms.<p> |
|
|
|
<h3>Opting for LGPL</h3> |
|
|
|
For licensee's opting to use Shapelib under LGPL as opposed to the MIT |
|
Style license above, and wishing to redistribute the software based on |
|
Shapelib, I would ask that all "dual license" modules be updated to |
|
indicate that only the LGPL (and not the MIT Style license) applies. This |
|
action represents opting for the LGPL, and thereafter LGPL terms apply to |
|
any redistribution and modification of the affected modules.<p> |
