+Usage is: extract_holdings -p PREFIX -m MARCFILE [ARGUMENTS]
+
+REQUIRED ARGUMENTS
+ --prefix -p Prefix string for output filenames
+ --marcfile -m MARCXML to use as source data
+
+SAMPLING ARGUMENTS
+ --sample -s Generate a report of all tags in the MARC data
+ --samplemap -sm Specify a E::M::STL map file which will be used to generate
+ subfield breakdown reports about specific tags in the MARC
+ data
+ --samplestr -ss As above, but with a one-liner map specified on the command
+ line as a string (e.g. '-ss "852 999"')
+
+ If --samplemap and --samplestr are both specified, --samplemap wins.
+
+HOLDINGS EXTRACTION ARGUMENTS
+ --map E::M::SM map file which will be 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
+
+ Both these must be given together.
