#  ssh setup to send to shell.sf.net and $CF without password prompt
#  the compile server has all the prerequisites stated at http://nagiosplug.sourceforge.net/developer-guidelines.html
# Install in cron with something like:
#  47 * * * * $HOME/bin/mail_error -o $HOME/sfsnapshot.out -m tonvoon@users.sf.net sfsnapshot r1_3_0
