# HOW TO USE THIS SCRIPT 
#
#  Executing the script like the following will run the build and, in
#  the event of a failure, send an email message to
#  scm@geronimo.apache.org with a link to the build output and a small
#  snippit of maven output.
#
#   $ ./build_and_complain.sh 
#
#  Executing the script like the following will do the same as above, 
#  but send the build output to foobar@apache.org
#
#   $ ./build_and_complain.sh foobar@apache.org
#
# DETAILS
#
#  On failure, the script will scp build data to your public_html 
#  directory on people.apache.org.  If your keys aren't setup, this 
#  won't work so well.
#

### begin email output ###

  $(grep 'Checked out revision' $LOG | sed 's/Checked out r/R/' )

See details at:

Simple grep of build output:

$(grep -C 10 FAILED $LOG | perl -pe 's/^--$/\n[SNIP]\n/; s/^/  /')
