# This script processes *.{sum,log} files, producing a shell-script

# that sends e-mail to the appropriate lists and renames files to

# *.sent.  It currently handles only gcc, but it should be quite easy

# to modify it to handle other packages and its mailing lists.

# The scripts assumes it is run in the root directory of the build

# tree, and it will include all .sum files it finds in the mail

# report.

# configure flags are extracted from ./config.status

# if the BOOT_CFLAGS environment variable is set, it will be included

# in the mail report too.

# The usage pattern of this script is as follows:

# test_summary | more   # so as to observe what should be done

# test_summary | sh     # so as to actually send e-mail and move log files

# It accepts a few command line arguments.  For example:

if test x"$1" = "x-h"; then

  cat <<_EOF

 -o: re-reads logs that have been mailed already (.sum.sent)

 -t: prevents logs from being renamed

 -p: prepend specified file (or list of files: -p "a b") to the report

 -i: append specified file (or list of files: -i "a b") to the report

 -m: specify the e-mail address to send notes to.  An appropriate default

     should be selected from the log files.

 -f: force reports to be mailed; if omitted, only reports that differ

     from the sent.* version are sent.
