			BibUpload: Receive MARC XML file and update the appropriate database
			tables according to options.

			Usage: bibupload [options] input.xml
			Examples:
			$ bibupload -i input.xml

			Options:
			-a, --append new fields are appended to the existing record
			-c, --correct fields are replaced by the new ones in the
			existing record
			-f, --format takes only the FMT fields into account.
			Does not update
			-i, --insert insert the new record in the database
			-r, --replace the existing record is entirely replaced
			by the new one
			-z, --reference update references (update only 999 fields)
			-s, --stage=STAGE stage to start from in the algorithm
			(0: always done; 1: FMT tags;
			2: FFT tags; 3: BibFmt; 4: Metadata update; 5: time update)
			-n, --notimechange do not change record last modification date
			when updating
			-o, --holdingpen Makes bibupload insert into holding pen instead
			the normal database
			Scheduling options:
			-u, --user=USER user name to store task, password needed

			General options:
			-h, --help print this help and exit
			-v, --verbose=LEVEL verbose level (from 0 to 9, default 1)
			-V --version print the script version
