# This file lists the source files that are expected to be excluded from
# Coverity's analysis, and the reason why.
#

# The expected format is an array of tuples (filename_pattern, description).
# - filename_pattern is a Python regular expression (as in the 're' module)
#   describing the file(s) to exclude.
# - description aims at providing the reason why the files are expected
#   to be excluded.
