__doc__ = """This command creates a new URI Reference resource in a \
4Suite repository. A URI Reference resource is like a Raw File but \
its content is always obtained on demand by dereferencing the stored \
URI. The first dereference operation occurs when this command is run, \
so the resource identified by the URI must be retrievable at that \
time. Resource metadata (size, etc.) from the last dereference \
operation is stored in the repository. Media type information is not \
obtained automatically; if a media type is not given on the command \
line, it will default to text/plain. If necessary, you will be \
prompted first for credentials and access info to connect to the \
repository."""
