Here's a script to use a wiki page for an automated build report. In this example, git-svn is used as revision control system. The script is intended to run as a cron-job.

# get current and last revision
SVNREV=`git svn log --oneline --limit=1 | sed 's/r\([0-9]*\).*/\1/'`
 
# make sure it exists
if [ ! -f $LASTREVTXT ]
then
  echo "0" >$LASTREVTXT
fi
 
LASTREV=`cat $LASTREVTXT`
 
# exit if we already compiled this revision
if [ $SVNREV -eq $LASTREV ]
then
  exit 0
