=== picurl.util ===
picurl.util uses some utility functions borrowed from other sources:
 * ''Cross-platform which-emulation based on a method from Mark Lutz' launcher.py (example script released with [http://www.oreilly.com/catalog/python3/ Programming Python, 3rd Edition, O'Reilly])''

== External, optional Dependencies ==
For standard use cases, picurl is designed to run 'out-of-the-box' and doesn't require any external program. To enable advanced functions (Camera Raw support, advanced metadata parsing), picurl needs the following external programs:
 * [http://www.sno.phy.queensu.ca/~phil/exiftool/ Exiftool], licensed under the [http://dev.perl.org/licenses/ Perl License]
 * [http://cybercom.net/~dcoffin/dcraw/ dcraw], [http://www.lebsanft.org/blog/?tag=dcraw dcraw Windows Binaries], unknown license
 * [http://www.imagemagick.org/ ImageMagick], licensed under the [http://www.imagemagick.org/script/license.php GPL-compatible ImageMagick License]

NOTE: These tools will not ship with picurl and have to be downloaded separately. picurl can auto-detect the presence of these tools, if they are in your system path. On Linux or MacOS X, this is done automatically. On Windows, you have to add the installation path of the tool to the environment variable PATH.
