#
# Load the JSON format of a presentation, convert it to the DSL format,
# and then send it to the DSL parser. This parser is to provide backwards
# compatabiliy to the previously defined JSON format of a Parade presentation.
#
# @example parade.json format
#
# {
# "name": "Something",
# "description": "Example Presentation",
# "templates" : { "default" : "custom.tpl" },
# "sections": [
# {"section":"one"},
# {"section":"two"},
# {"section":"three"}
# ]
# }
