#!/usr/bin/perl
# This script reads a block of message headers on stdin, and converts them
# to an emacs-lisp string (quoting all dangerous characters) and then
# uses the `gnudoit' program to cause a running Emacs process to invoke
# the `bbdb-srv' function with that string.
#
# This has the effect of causing the running Emacs to display the BBDB
# record corresponding to these headers.
#
# See the Emacs side of things in bbdb-srv.el for more info.
#
# A trivial application of this is the shell command:
#
# echo 'From: Jamie Zawinski <jwz@netscape.com>' | bbdb-srv.perl
#
# which will cause the corresponding record to be displayed.
# A more interesting application of this is:
#
# setenv NS_MSG_DISPLAY_HOOK bbdb-srv.perl
#
# which will hook BBDB up to Mozilla (Unix Netscape Mail and Netscape News
# versions 3.0b2 and later only.)
#
# -- Jamie Zawinski <jwz@netscape.com>, 25-apr-96
# spawn in the background and return to the caller immediately.
