.SH Description
.\" ====================================================================
.
.I \%lkbib
searches bibliographic databases for references containing keywords
.I key
and writes any references found to the standard output
stream.
.
It reads databases given by
.B \-p
options
and then
(unless
.B \-n
is given)
a default database.
.
The default database is taken from the
.I \%REFER
environment variable if it is set,
otherwise it is
.IR /usr/\:\%dict/\:\%papers/\:\%Ind .
.
For each database
.I file
to be searched,
if an index
.RI file \%.i
created by
.MR \%indxbib 1
exists,
then it will be searched instead;
each index can cover multiple databases.
.
.
