call it with:

checkit_tiff [-c|-h|-m|-d] <tifffile> <configfile>

where <tifffile> is the tiff file (or directory) to be validated and <configfile> is the file name of the validation profile

-h this help

-c colorized output using ANSI escape sequences

-m uses memmapped I/O (faster validation, but needs more RAM)

-d check all files in that directory

example:

checkit_tiff tiffs_should_pass/minimal_valid.tiff example_configs/baseline_minimal.cfg
