SConstruct for libtiff
The libtiff homepage is LibTIFF - TIFF Library and Utilities. Get the library itself here. This is setup to use MinGW by default. If you want to use another compiler or OS you may need to play with it a bit, but not much. This script uses features from Python 2.6 (print function and with statement). If you are using 2.5.x or below you will either need to upgrade or modify this file appropriately.
