.TH REFER 1 "8 February 1983"
.SH NAME
refer \- find and insert literature references in documents
.SH SYNOPSIS
.B refer
[ option ... ]
.SH DESCRIPTION
.I Refer
is a preprocessor for 
.IR nroff (1),
or
.IR troff (1),
that finds and formats references.  The input files (standard input by
default) are copied to the standard output, except for lines between .[
and .] command lines.  Such lines are assumed to contain keywords as for
.IR lookbib (1),
and are replaced by information from a bibliographic data base.  The
user can avoid the search, override fields from it, or add new fields.
The reference data, from whatever source, is assigned to a set of 
.I troff
strings.  Macro packages such as 
.IR ms (7)
print the finished reference text from these strings.  A flag is placed
in the text at the point of reference.  By default, the references are
indicated by numbers.
.LP
The following options are available:
.TP
.BI -a r
Reverse the first 
.I r
author names (Jones, J. A. instead of J. A. Jones).  If 
.I r
is omitted, all author names are reversed.
.TP
.B -b
Bare mode \(em do not put any flags in text (neither numbers or labels).
.TP
.BI -c string
Capitalize (with C\s-2APS\s+2 S\s-2MALL\s+2 SC\s-2APS\s+2) the fields
whose key-letters are in 
.IR string .
.TP
.B -e
Instead of leaving the references where encountered, accumulate them
until a sequence of the form:
.nf
.in +1.0i
\&.[
$LIST$
\&.]
.fi
.in -1.0i
is encountered, and then write out all references collected so far.
Collapse references to the same source.
.TP
.BI -k x
Instead of numbering references, use labels as specified in a reference
data line beginning with the characters 
.IR %x ;
By default, 
.I x
is
.BR L .
.TP
.RI -l m , n
Instead of numbering references, use labels from the senior author's
last name and the year of publication.  Only the first
.I m
letters of the last name and the last 
.I n
digits of the date are used.  If either of 
.IR m or ,n
is omitted, the entire name or date respectively is used.
.TP
.B -p
Take the next argument as a file of references to be searched.  The
default file is searched last.
.TP
.B -n
Do not search the default file.
.TP
.BI -s keys
Sort references by fields whose key-letters are in the 
.I keys
string, and permute reference numbers in the text accordingly.  Using
this option implies the 
.B -e
option.  The key-letters in
.I keys
may be followed by a number indicating how many such fields are used,
with a + sign taken as a very large number.  The default is 
.BR AD ,
which sorts on the senior author and date.  To sort on all authors and
then the date, for instance, use the options 
.BR -sA+T .
.LP
When
.I Refer
is used with
.IR eqn (1),
.IR neqn (1),
or
.IR tbl (1),
.I Refer
should be used fits in the sequence, to minimize the volume of data
passed through pipes.
