# This script transforms the output of GCC's contrib/test_summary (an
# email) into a format suitable for consumption by our Jenkins CI:
# three files, containing subject, recipients and body.
#
# In order to be used transparently as a replacement for "Mail",
# it uses the same interface as the "Mail" command:
#
# cat body | testresults2jenkins.sh -s "subject" "recipients"
#
# its output goes intro three files:
# - testresults-mail-recipients.txt
# - testresults-mail-subject.txt
# - testresults-mail-body.txt
#
# Because of the fixed interface, we use an environment variable to
# specify the output directory and prefix (TESTRESULTS_PREFIX).
