DESCRIPTION
    sa-compile uses "re2c" to compile the site-wide parts of the
    SpamAssassin ruleset. No part of user_prefs or any files included from
    user_prefs can be built into the compiled set.

    This compiled set is then used by the
    "Mail::SpamAssassin::Plugin::Rule2XSBody" plugin to speed up
    SpamAssassin's operation, where possible, and when that plugin is
    loaded.

    "re2c" can match strings much faster than perl code, by constructing a
    DFA to match many simple strings in parallel, and compiling that to
    native object code. Not all SpamAssassin rules are amenable to this
    conversion, however.

    This requires "re2c" (see "http://re2c.org/"), and the C compiler used
    to build Perl XS modules, be installed.

    Note that running this, and creating a compiled ruleset, will have no
    effect on SpamAssassin scanning speeds unless you also edit your
    "v320.pre" file and ensure this line is uncommented:

      loadplugin Mail::SpamAssassin::Plugin::Rule2XSBody

OPTIONS
    --list
        Output the extracted base strings to STDOUT, instead of generating
        the C extension code.

    --sudo
        Use sudo(8) to run code as 'root' when writing files to the
        compiled-rules storage area (which is
        "/home/parker/perl5/perlbrew/perls/perl-5.14.1/var/spamassassin/comp
        iled/5.014/3.003003" by default).

    --quiet
        Produce less diagnostic output. Errors will still be displayed.

    --keep-tmps
        Keep temporary files after the script completes, instead of deleting
        them.

    -C *path*, --configpath=*path*, --config-file=*path*
        Use the specified path for locating the distributed configuration
        files. Ignore the default directories (usually
        "/usr/share/spamassassin" or similar).

    --siteconfigpath=*path*
        Use the specified path for locating site-specific configuration
        files. Ignore the default directories (usually
        "/etc/mail/spamassassin" or similar).

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

                /home/parker/perl5/perlbrew/perls/perl-5.14.1/var/spamassassin/compiled/5.014/3.003003

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

        Note that use of this option is not recommended; if sa-compile is
        placing the compiled rules the wrong directory, you probably need to
        rebuild SpamAssassin with different "Makefile.PL" arguments, instead
        of overriding sa-compile's runtime behaviour.

    --cf='config line'
        Add additional lines of configuration directly from the
        command-line, parsed after the configuration files are read.
        Multiple --cf arguments can be used, and each will be considered a
        separate line of configuration.

    -p *prefs*, --prefspath=*prefs*, --prefs-file=*prefs*
        Read user score preferences from *prefs* (usually
        "$HOME/.spamassassin/user_prefs") .

    -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 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-compile version and exit.
