# check the forensic log for requests that did not complete
# output the request log for each one

# This script is based on Ben Laurie's check_forensic, but is adjusted for GNU
# tools (as used on Linux) and it works in a safe tmpdir directory. 
# todo: rewrite in a form that allows running on more operating systems.
