# There is a templating error preventing this file from rendering correctly.
#
# This is most likely not due to a bug in Cobbler and is something you can fix.
#
# Look at the message below to see what things are causing problems.  
#
# (1) Does the template file reference a $variable that is not defined?
# (2) is there a formatting error in a Cheetah directive?
# (3) Should dollar signs ($) be escaped that are not being escaped?
#
# Try fixing the problem and then investigate to see if this message goes
# away or changes.
