# This script is called by recollindex to determine if it would be
# worth retrying files which previously failed to index.
#
# This is the default implementation, it is pointed to by the
# 'checkneedretryindexscript' variable in the default recoll.conf
#
# The script exits with 0 if retrying should be performed (something
# changed), 1 else.
#
# We check /usr/bin and /usr/local/bin modification date against the
# previous value recorded inside ~/.config/Recoll.org/needidxretrydate
#
# If any argument is given, we record the new state instead of
# generating it (this should be used at the end of an indexing pass
# with retry set).
