Something as simple as

from calibre.ebooks.oeb.polish.check.main import run_checks, fix_errors
from calibre.ebooks.oeb.polish.container import get_container

import sys
filepath = sys.argv[-1]
container = get_container(filepath, tweak_mode=True)
errors = run_checks(container)
if errors:
    print ('Found errors, trying to fix them')
    if fix_errors(container, errors):
        container.commit()

Thanks eschwartz, thanks kovidgoyal!

It is very useful information for me! I'm familiar with python, but not familiar with Calibre yet. Can you help me, or give me a link, that can explain, how to run this script in Calibre? Such a quick start to scripting.

Thanks again,
Georgy
