Batch processing of image data

The latest version of Bilko also offers limited support for batch-processing of image data from the Windows Command line. This is based on Bilko sets (lists of files and parameters to be extracted from these) and formula documents (mini-programs) containing processing instructions. The batch processing capability is currently being tested by selected Bilko users.
