# For a specified tool and optional list of test variants, extract
# test results from one or more test summary (.sum) files and combine
# the results into a new test summary file, sent to the standard output.
# The resulting file can be used with test result comparison scripts for
# results from tests that were run in parallel. See usage() below.

Usage: $PROGNAME [-t tool] [-l variant-list] [-L] sum-file ...
tool The tool (e.g. g++, libffi) for which to create a
new test summary file. If not specified then all
specified sum files must be for the same tool.
variant-list One or more test variant names. If the list is
not specified then one is constructed from all
variants in the files for <tool>.
sum-file A test summary file with the format of those
created by runtest from DejaGnu.
If -L is used, merge *.log files instead of *.sum. In this
mode the exact order of lines may not be preserved, just different
Running *.exp chunks should be in correct order.
