This script exports MARC authority, bibliographic, and serial holdings
records from an Evergreen database. 

Input to this script can consist of a list of record IDs, with one record ID
per line, corresponding to the record ID in the Evergreen database table of
your requested record type.

Alternately, passing the --all option will attempt to export all records of
the specified type from the Evergreen database. The --all option starts at
record ID 1 and increments the ID by 1 until the largest ID in the database
is retrieved. This may not be very efficient for databases with large gaps
in their ID sequences.

Usage: $0 [options]
 --help or -h       This screen.
 --config or -c     Configuration file [/openils/conf/opensrf_core.xml]
 --format or -f     Output format (USMARC, UNIMARC, XML, BRE, ARE) [USMARC]
 --encoding or -e   Output encoding (UTF-8, ISO-8859-?, MARC8) [MARC8]
 --xml-idl or -x    Location of the IDL XML
 --timeout          Timeout for exporting a single record; increase if you
                    are using --holdings and are exporting records that
                    have a lot of items attached to them.
 --type or -t       Record type (BIBLIO, AUTHORITY) [BIBLIO]
 --all or -a        Export all records; ignores input list

 Additional options for type = 'BIBLIO':
 --items or -i      Include items (holdings) in the output
 --money            Currency symbol to use in item price field [\$]
 --mfhd             Export serial MFHD records for associated bib records
                    Not compatible with --format=BRE
 --location or -l   MARC Location Code for holdings from
                    http://www.loc.gov/marc/organizations/orgshome.html

 Options added by Sitka:
 --force901                 Force-add 901 fields
 --exclusion_ini FILENAME   Config::Simple based INI file for excluding holdings from the export
 --collapse_to_depth 2      Depth to collapse holdings.  Any holdings at a depth below 
                            will be collapsed up to the parent org unit at the set depth
 --onlyholdings             Clean out 852s before adding new ones, and only export items that
                            successfully recieved an 852 field

Examples:

To export a set of USMARC records in a file named "output_file" based on the
IDs contained in a file named "list_of_ids":
  cat list_of_ids | $0 > output_file

To export a set of MARC21XML authority records in a file named "output.xml"
for all authority records in the database:
  $0 --format XML --type AUTHORITY --all > output.xml
