REQUIRED ARGUMENTS
--prefix -p Prefix string for output filenames
used to extract holdings data from the input MARC file
--holdings -h Specifies actual holdings tag
--copyid -c Specifies subfield of holdings with unique copy identifier
+ --disable-pg-normalization By default, output is normalized so that a Postgres
+ copy or \\copy can import the data without choking on
+ backslashes; use this command-line option if
+ output is not meant to be consumed by psql.
All three of these must be given together.
