As of 0.3.1, lensfun includes support for my Canon S100 CR2 raw.  This
solves stuff like http://www.dpreview.com/forums/post/51970815 where the
pole at the far right shows "barrel effect".  I actually have 0.3.0 (the
latest "unstable" in Gentoo linux) and I've stuck in the XML data files
from 0.3.1.0.  As mentioned above, I run linux.

  The next problem is how to do it from the command line.  After
shooting a lot of photos in a day, I do not want to have to...

* manually open each CR2 in gimp via the ufraw plugin
* Click OK to accept the ufraw load 
* manually apply lensfun

...100 or 200 times in a row.  I need a command line tool like
http://lensfun.sourceforge.net/manual/lenstool_8cpp-example.html for my
"workflow".  I'm not a C/C++ programmer, but I can compile the code if
given instructions.  Is it possible to run lenstool, giving it input and
and output file names, and whatever else, to get it to do the correction
for distortion from the commandline?

  I have the perl "exiftool" utility that can read exif data from the
CR2 file to pass on to lenstool.  My main worry is that I have lensfun
0.3.0 (the latest lensfun available on Gentoo linux), and the lenstool
code is for 0.3.1.0.  Are they compatable?
