What information exactly do you need?

Return codes. Return codes in case of "--on-error=resume" parameter. Return codes in case of "warning" message from ocr engine.
I use ocrodjvu to batch processing, and I need differentiate critical and non-critical errors in ocr process.
ocrodjvu doesn't pay attention to warnings generated by OCR engines.
--on-error=resume would normally cause exit code to be 0, even when processing one of the pages failed. (Although I think it's a bug, so it's subject to change.)
ocrodjvu also exits with 0 if it was interrupted by Ctrl+C. This is of course a bug; I'll get it fixed.

May be stop execution with non-zero exit code when some number pages failed (with --on-error=resume)?

And, is necessary return non-zero exit code with --on-error=resume parametr if execution crashes. So, processing of the file http://libgen.org/get?nametype=md5&md5=000745AD512BDC7ABF4F9977D6137411 crash:
- Page #417
*** page "419" not found
*** (djvused.cpp:371)
*** 'void verror(const char*, ...)'

, but return code is 0. Resulting djvu turn out is no ocr'd .
Agreeed. I'll get that fixed.

This file: http://libgen.org/get?nametype=orig&md5=6a9f527b3226f56f1fbccb7addbcba57 has only
- Page #1
No image suitable for OCR.
error on every page. As result, file is not ocr'd, but result code is 0.
The problem with Ctrl+C was fixed in 0.7.17.
In 6bd704f66eb6afcd17bf961e6a2cdb4325f262cb, I made ocrodjvu exit with code 2 if it resumed from an error. This will be part of ocrodjvu 0.8.
I haven't decided yet what to do with the case when there's “No image suitable for OCR” on every page.
I'd like to credit you in the changelog. Could you tell me what is your full name?
I've just released ocrodjvu 0.8.
Feel free to open a new bug about the case when there's “No image suitable for OCR” on every page.

The "No image suitable for OCR" error in every page still occurs for me with ocrodjvu 0.9.1 and tesseract. However the images in my file are 600x600 dpi and very clear, in fact tesseract works perfectly on each individual image page.
Anyway, a small glitch, thanks a lot Jakub for a fantastic program.
