DESCRIPTION
       sa-update automates the process of downloading and installing new rules and configuration,
       based on channels.  The default channel is updates.spamassassin.org, which has updated
       rules since the previous release.

       Update archives are verified using SHA1 hashes and GPG signatures, by default.

       Note that "sa-update" will not restart "spamd" or otherwise cause a scanner to reload the
       now-updated ruleset automatically.  Instead, "sa-update" is typically used in something
       like the following manner:

	       sa-update && /etc/init.d/spamassassin reload

       This works because "sa-update" only returns an exit status of 0 if it has successfully
       downloaded and installed an updated ruleset.

OPTIONS
       --channel
	   sa-update can update multiple channels at the same time.  By default, it will only
	   access "updates.spamassassin.org", but more channels can be specified via this option.
	   If there are multiple additional channels, use the option multiple times, once per
	   channel.  i.e.:

		   sa-update --channel foo.example.com --channel bar.example.com

       --channelfile
	   Similar to the --channel option, except specify the additional channels in a file
	   instead of on the commandline.  This is useful when there are a lot of additional
	   channels.

       --checkonly
	   Only check if an update is available, don't actually download and install it.  The
	   exit code will be 0 or 1 as described below.

       --install
	   Install updates "offline", from the named tar.gz file, instead of performing DNS
	   lookups and HTTP invocations.

	   Files named file.sha1 and file.asc will be used for the SHA-1 and GPG signature,
	   respectively.  The filename provided must contain a version number of at least 3
	   digits, which will be used as the channel's update version number.

	   Multiple --channel switches cannot be used with --install.  To install multiple
	   channels from tarballs, run "sa-update" multiple times with different --channel and
	   --install switches, e.g.:

		   sa-update --channel foo.example.com --install foo-34958.tgz
		   sa-update --channel bar.example.com --install bar-938455.tgz

       --allowplugins
	   Allow downloaded updates to activate plugins.  The default is not to activate plugins;
	   any "loadplugin" or "tryplugin" lines will be commented in the downloaded update rules
	   files.

       --gpg, --nogpg
	   sa-update by default will verify update archives by use of a SHA1 checksum and GPG
	   signature.  SHA1 hashes can verify whether or not the downloaded archive has been
	   corrupted, but it does not offer any form of security regarding whether or not the
	   downloaded archive is legitimate (aka: non-modifed by evildoers).  GPG verification of
	   the archive is used to solve that problem.

	   If you wish to skip GPG verification, you can use the --nogpg option to disable its
	   use.  Use of the following gpgkey-related options will override --nogpg and keep GPG
	   verification enabled.

	   Note: Currently, only GPG itself is supported (ie: not PGP).  v1.2 has been tested,
	   although later versions ought to work as well.

       --gpgkey
	   sa-update has the concept of "release trusted" GPG keys.  When an archive is
	   downloaded and the signature verified, sa-update requires that the signature be from
	   one of these "release trusted" keys or else verification fails.  This prevents third
	   parties from manipulating the files on a mirror, for instance, and signing with their
	   own key.

	   By default, sa-update trusts key id "265FA05B", which is the standard SpamAssassin
	   release key.  Use this option to trust additional keys.  See the --import option for
	   how to add keys to sa-update's keyring.  For sa-update to use a key it must be in sa-
	   update's keyring and trusted.

	   For multiple keys, use the option multiple times.  i.e.:

		   sa-update --gpgkey E580B363 --gpgkey 298BC7D0

	   Note: use of this option automatically enables GPG verification.

       --gpgkeyfile
	   Similar to the --gpgkey option, except specify the additional keys in a file instead
	   of on the commandline.  This is extremely useful when there are a lot of additional
	   keys that you wish to trust.

       --gpghomedir
	   Specify a directory path to use as a storage area for the "sa-update" GPG keyring.  By
	   default, this is

		   /etc/mail/spamassassin/sa-update-keys

       --import
	   Use to import GPG key(s) from a file into the sa-update keyring which is located in
	   the directory specified by --gpghomedir.  Before using channels from third party
	   sources, you should use this option to import the GPG key(s) used by those channels.
	   You must still use the --gpgkey or --gpgkeyfile options above to get sa-update to
	   trust imported keys.

	   To import multiple keys, use the option multiple times.  i.e.:

		   sa-update --import channel1-GPG.KEY --import channel2-GPG.KEY

	   Note: use of this option automatically enables GPG verification.

       --refreshmirrors
	   Force the list of sa-update mirrors for each channel, stored in the MIRRORED.BY file,
	   to be updated.  By default, the MIRRORED.BY file will be cached for up to 7 days after
	   each time it is downloaded.

       --updatedir
	   By default, "sa-update" will use the system-wide rules update directory:

		   /var/lib/spamassassin/3.003002

	   If the updates should be stored in another location, specify it here.

	   Note that use of this option is not recommended; if you're just using sa-update to
	   download updated rulesets for a scanner, and sa-update is placing updates in the wrong
	   directory, you probably need to rebuild SpamAssassin with different "Makefile.PL"
	   arguments, instead of overriding sa-update's runtime behaviour.

       -D [area,...], --debug [area,...]
	   Produce debugging output.  If no areas are listed, all debugging information is
	   printed.  Diagnostic output can also be enabled for each area individually; area is
	   the area of the code to instrument. For example, to produce diagnostic output on
	   channel, gpg, and http, use:

		   sa-update -D channel,gpg,http

	   For more information about which areas (also known as channels) are available, please
	   see the documentation at <http://wiki.apache.org/spamassassin/DebugChannels>.

       -h, --help
	   Print help message and exit.

       -V, --version
	   Print sa-update version and exit.

EXIT CODES
       An exit code of 0 means an update was available, and was downloaded and installed
       successfully if --checkonly was not specified.

       An exit code of 1 means no fresh updates were available.

       An exit code of 2 means that at least one update is available but that a lint check of the
       site pre files failed.  The site pre files must pass a lint check before any updates are
       attempted.

       An exit code of 4 or higher, indicates that errors occurred while attempting to download
       and extract updates.
