+# This program is designed to run from the loginfo CVS administration file. It
+# takes a log message, massaging it and mailing it to the address given below.
+#
+# Its record in the loginfo file should look like:
+#
+#       ALL        $CVSROOT/CVSROOT/ciabot.pl %s $USER project from_email dest_email ignore_regexp
+#
+# Note that the last four parameters are optional, you can alternatively change
+# the defaults below in the configuration section.
+#
+# If it does not work, try to disable $xml_rpc in the configuration section
+# below.

+### Configuration
+
+# Project name (as known to CIA).
+$project = 'ELinks';
+
+# The from address in generated mails.
+$from_email = 'pasky@ucw.cz';
+
+# Mail all reports to this address.
+$dest_email = 'cia@navi.cx';
+
+# If using XML-RPC, connect to this URI.
+$rpc_uri = 'http://cia.navi.cx/RPC2';
+
+# Path to your USCD sendmail compatible binary (your mailer daemon created this
+# program somewhere).
+$sendmail = '/usr/sbin/sendmail';
+
+# Number of seconds to wait for possible concurrent instances. CVS calls up
+# this script for each involved directory separately and this is the sync
+# delay. 5s looks as a safe value, but feel free to increase if you are running
+# this on a slower (or overloaded) machine or if you have really a lot of
+# directories.
+$sync_delay = 5;
+
+# This script can communicate with CIA either by mail or by an XML-RPC
+# interface. The XML-RPC interface is faster and more efficient, however you
+# need to have RPC::XML perl module installed, and some large CVS hosting sites
+# (like Savannah or Sourceforge) might not allow outgoing HTTP connections
+# while they allow outgoing mail. Also, this script will hang and eventually
+# not deliver the event at all if CIA server happens to be down, which is
+# unfortunately not an uncommon condition.
+$xml_rpc = 0;
+
+# You can make this bot to totally ignore events concerning the objects
+# specified below. Each object is composed of <module>/<path>/<filename>,
+# therefore file Manifest in root directory of module gentoo will be called
+# "gentoo/Manifest", while file src/bfu/inphist.c of module elinks will be
+# called "elinks/src/bfu/inphist.c". Easy, isn't it?
+#
+# This variable should contain regexp, against which will each object be
+# checked, and if the regexp is matched, the file is ignored. Therefore ie.  to
+# ignore all changes in the two files above and everything concerning module
+# 'admin', use:
+#
+#$ignore_regexp = "^(gentoo/Manifest|elinks/src/bfu/inphist.c|admin/)";
+$ignore_regexp = "/Manifest\$";
+
+# It can be useful to also grab the generated XML message by some other
+# programs and ie. autogenerate some content based on it. Here you can specify
+# a file to which it will be appended.
