# Sample usage in crontab:
# Run, Mon-Fri at 1:30am. Add to build user's crontab.
#   30 1 * * 1-5 . /jds/cbe/bin/env.sh; I_KNOW_WHAT_IM_DOING=yes myEnv=nightly-beijing.env $0
#
# The same with a jail. Add to root's crontab. Example assumes 'gbuild' is the
# build user
#   30 1 * * 1-5 /usr/sbin/chroot /path/to/jail/root /usr/bin/su - gbuild -c ". /jds/cbe/bin/env.sh; I_KNOW_WHAT_IM_DOING=yes myEnv=nightly-beijing.env $0"

# Or - you may choose to only build a particular package

# History:
# --------
#
# Damien Carbery:
#       cron-script.sh, original script
#
# Alexandre Berman:
#       based on the original script, created cron-nightly.sh
#       added/changed features:
#         - added sub-routines for easy debugging, clarity
#         - changed to SVN (original script used cvs)
#         - took all site-dependent variable declarations out of the script and adopted it to use env file
#         - added support for building individual components (must specify spec file), useful for debugging and others..
#         - added more verbosity to the script for debugging and clarity

if [ -r $myEnv ]; then
   . $myEnv # setup our env
