Imagine using cuneiform to batch process a document there one page is a
blank page, clearly you do not want the cuneiform program to report a
crash for the blank page.

There are alternatives for what exactly should happen. Two options which would make more sense compared to reporting an error code:
* exit with a normal exit code and no output
* exit with a normal exit code with the output of the specified format (i.e. empty textfile or a .hocr file with the standard meta tags but no textlines etc).


Personally I would prefer the latter as an empty page is also important to be able to scan correctly (i.e. that no noise character are outputted for example).

Assume it is a test case to be written for cuneiform, say that version
(A) of cuneiform exits with an error code as is today, (B) cuneiform
exits with a normal status code but no output is produced, (C) as option
(B) but with output produced.

test case for (A)
 * process images, check if there is a crash and assume that means the page is blank, compare with ground truth

test case for (B)
 * process images, check if no output was produced for any file and assume that means an empty page and compare with ground truth

test case for (C)
 * process images, compare output with ground truth
 and so producing the output and to check against it wit.

Best regards,
Julien
