+#!/usr/bin/perl
+#
+# A daemon that waits for update events sent by its companion
+# post-receive-cinotify hook, checks out a new copy of source,
+# compiles it, and emails the guilty parties if the compile
+# (and optionally test suite) fails.
+#
+# To use this daemon, configure it and run it.  It will disconnect
+# from your terminal and fork into the background.  The daemon must
+# have local filesystem access to the source repositories, as it
+# uses objects/info/alternates to avoid copying objects.
+#
+# Add its companion post-receive-cinotify hook as the post-receive
+# hook to each repository that the daemon should monitor.  Yes, a
+# single daemon can monitor more than one repository.
+#
+# To use multiple daemons on the same system, give them each a
+# unique queue file and tmpdir.
+#
+# Global Config
+# -------------
+# Reads from a Git style configuration file.  This will be
+# ~/.gitconfig by default but can be overridden by setting
+# the GIT_CONFIG_FILE environment variable before starting.
+#
+# cidaemon.smtpHost
+#   Hostname of the SMTP server the daemon will send email
+#   through.  Defaults to 'localhost'.
+#
+# cidaemon.smtpUser
+#   Username to authenticate to the SMTP server as.  This
+#   variable is optional; if it is not supplied then no
+#   authentication will be performed.
+#
+# cidaemon.smtpPassword
+#   Password to authenticate to the SMTP server as.  This
+#   variable is optional.  If not supplied but smtpUser was,
+#   the daemon prompts for the password before forking into
+#   the background.
+#
+# cidaemon.smtpAuth
+#   Type of authentication to perform with the SMTP server.
+#   If set to 'login' and smtpUser was defined, this will
+#   use the AUTH LOGIN command, which is suitable for use
+#   with at least one version of Microsoft Exchange Server.
+#   If not set the daemon will use whatever auth methods
+#   are supported by your version of Net::SMTP.
+#
+# cidaemon.email
+#   Email address that daemon generated emails will be sent
+#   from.  This should be a useful email address within your
+#   organization.  Required.
+#
+# cidaemon.name
+#   Human friendly name that the daemon will send emails as.
+#   Defaults to 'cidaemon'.
+#
+# cidaemon.scanDelay
+#   Number of seconds to sleep between polls of the queue file.
+#   Defaults to 60.
+#
+# cidaemon.recentCache
+#   Number of recent commit SHA-1s per repository to cache and
+#   skip building if they appear again.  This is useful to avoid
+#   rebuilding the same commit multiple times just because it was
+#   pushed into more than one branch.  Defaults to 100.
+#
+# cidaemon.tmpdir
+#   Scratch directory to create the builds within.  The daemon
+#   makes a new subdirectory for each build, then deletes it when
+#   the build has finished.  The pid file is also placed here.
+#   Defaults to '/tmp'.
+#
+# cidaemon.queue
+#   Path to the queue file that the post-receive-cinotify hook
+#   appends events to.  This file is polled by the daemon.  It
+#   must not be on an NFS mount (uses flock).  Required.
+#
+# cidaemon.nocc
+#   Perl regex patterns to match against author and committer
+#   lines.  If a pattern matches, that author or committer will
+#   not be notified of a build failure.
+#
+# Per Repository Config
+# ----------------------
+# Read from the source repository's config file.
+#
+# builder.command
+#   Shell command to execute the build.  This command must
+#   return 0 on "success" and non-zero on failure.  If you
+#   also want to run a test suite, make sure your command
+#   does that too.  Required.
+#
+# builder.queue
+#   Queue file to notify the cidaemon through.  Should match
+#   cidaemon.queue.  If not set the hook will not notify the
+#   cidaemon.
+#
+# builder.skip
+#   Perl regex patterns of refs that should not be sent to
+#   cidaemon.  Updates of these refs will be ignored.
+#
+# builder.newBranchBase
+#   Glob patterns of refs that should be used to form the
+#   'old' revions of a newly created ref.  This should set
+#   to be globs that match your 'mainline' branches.  This
+#   way a build failure of a brand new topic branch does not
+#   attempt to email everyone since the beginning of time;
+#   instead it only emails those authors of commits not in
+#   these 'mainline' branches.
