# Definition: datacat

#

# This definition allows you to declare datacat managed files.

#

# Parameters:

# All parameters are as for the file type, with the addition of a $template

# parameter which is a path to a template to be used as the content of the

# file.

#

# Sample Usage:

#  datacat { '/etc/motd':

#    owner => 'root',

#    group => 'root,

#    template => 'motd/motd.erb',

#  }

#
