r2b-get-field

r2b-get-field is a compiled Lisp function in `refbib.el'.

(r2b-get-field VAR FIELD &optional UNIQUE REQUIRED CAPITALIZE)

Set VAR to string value of FIELD, if any. If none, VAR is set to
nil. If multiple fields appear, then separate values with the
'\nand\t\t', unless UNIQUE is non-nil, in which case log a warning
and just concatenate the values. Trim off leading blanks and tabs on
first line, and trailing blanks and tabs of every line. Log a warning
and set VAR to the empty string if REQUIRED is true. Capitalize as a
title if CAPITALIZE is true. Returns value of VAR.
