" This is the list of shelf codes.  The order is not important.  Comment
" lines begin with a doublequote, and blank lines are ignored.  The first
" column is the shelf codes as they must appear in the input file.  The
" optional second column is indicates that the shelf code is followed by
" a sequence number.  If the column is missing, then no sequence numbers
" are permitted.  If there is an asterisk, then at least one digit must
" be present.  If there is a number, then exactly that number of digits
" must be present (an error check).  The third column is the shelf code
" to use on output.  This is normally the same as the first column, but
" permits changing the shelf code on output, as a convenience.  The
" optional forth column permits changing the number of digits expected on
" output.  It is only permitted if the second column is also given.  With
" an asterisk, leading zeros are suppressed.  With a digit, leading zeros
" are inserted as necessary, but an error occurs if a nonzero digit
" doesn't fit.  The rest of the line is the printable shelf name, used in
" shelfdex.
