Looks ok. getopt_long is not standard, but I guess it's common enough. The one thing I'm a bit curious about is why the check if the number of images is zero was removed. Is there a point to creating a multi-image with zero images in it? |

Since pull request #92 doesn't appear to make any progress, I'm creating a pull request for the next part of the
icemultichanges without a test suite. This pull request introduces thegetoptlibrary for parsing command-line arguments, adds some missing error checks (for missing or empty input files and I/O errors) and provides more information with the existing error checks (program and file name).
