"""\
 Use PIL to make a contact sheet from a number of images.
 This program was inspired by the Life Poster described here:
 
 http://www.mikematas.com/blog/2005/01/how-to-make-life-poster.html

 I found that my version of IPhoto was too old to do everything,
 plus the Python Imaging Library makes this pretty easy to do.

 My suggestion is to follow the instructions for the life poster
 through step 2, since the constrained cropping is hard to do
 without a graphical interface. Then export those files into
 a directory, and use the attached script to make a contact sheet.

 You can save the resulting image (caution, it will be huge: mine
 was 155 MB), re-import it to IPhoto, and order a poster for yourself.
