# Name: fitsverify_file_strict
#
# Description: Runs several FITS-format verifiers against a file
#              to ensure that no FITS errors
#              are present.  The opus_fitsverify tool is used
#              for this purpose, run in a mode to only flag most errors
#              (the "strict" version distinguishes this version from the more
#               lenient fitsverify mode) and
#              also the pyFITS "verify" function is used.
#
# Called by:   fitsverify
#
# Returns: 0 = if no errors were found in the FITS files
#          1 = if errors were found
