	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
