# Quick and dirty shell script for taking a file with one package per line and
# turning that into valid YAML to use in conjunction with puppet-module-types
# and Hiera.
#
# Given a file, 'package_list' with contents
#
#   foo
#   bar
#   baz
#
# The following output is generated
#
#    types::packages:
#      'foo':
#        ensure: 'present'
#      'bar':
#        ensure: 'present'
#      'baz':
#        ensure: 'present'
