        replace bunches of /var/log/mail with get_log_dir

        install tcp.smtp during tests, if missing
        conf: removed vpopmail_enable_netblocks option (barely used, if at all)

        check just the 'standard' places for httpd.conf instead of using `find $dir`

         when a method is run, it can inherit its parents values for debug and

       create a single SSL cert and use it for qmail, dovecot, courier, apache
       courier imap startup scripts that broke due to FreeBSD changes are detected
         and fixed. rc.conf values are automatically updated by toaster_setup.pl
       default cgi-bin location changed to www/cgi-bin.toaster (statically defined
         will avoid problems when ports opt to install cgi-bin, or cgi-bin.default,
         or cgi-bin-default, or whatever comes next)

     t/maillogs - return a more specific error message if Date::Parse not installed

  5.03rc1 - Oct 15, 2006
    Packaging Updates
        Moved Params::Validate into inc directory (prevent CPAN from
        presuming I provide it), moved Changes back into doc/Changes.pod,
        added include lib "inc" into all test files (forgot that with 5.02
        release).

        Better pod descriptions for FreeBSD.pm, Mysql.pm, Apache.pm,
        Ezmlm.pm, Darwin.pm, DNS.pm, Provision.pm, Setup.pm, Passwd.pm,
        Perl.pm, and Toaster.pm. Updated META.yml to include license.

    FreeBSD Port preparations
        Default htdocs directory is now /usr/local/www/toaster.

    CPAN test tweaks
        Don't do passwd test on cygwin. Don't do network tests on Cygwin

     toaster-watcher.conf
       added install_roundcube option

     Darwin.pm
       updated $utility calls with MT 5 syntax updates
       udpated test file to use Test::More

     t/Utility.t
        only attempt to chown_system if we are root, don't run get_my_ips on 
        netbsd (until I figure out why it doesn't work

     Changes
       added file to distribution

     bin/toaster_setup.pl
       added RT URL to bug section for reporting

     bin/sysadmin
       updated for MT 5 syntax

     Passwd.pm 
        mt 5 syntax updates, add in warnings for failures

     Qmail.pm
       formatting cleanups, and added a few missing debug=>0 settings.

     Provision.pm
        mt 5 updates and rewrite. If values are missing and we are interactive,
           prompt for the missing values.
        pass debug and $conf variables in the $provision object (accomplish 
           the same result with less code)

     Utility.pm
       ask sub now returns $default value (instead of 0) if not interactive
       yes_or_no supports q shortcut for question argument

  5.02 - 2006.10.11
    toaster-watcher.conf
        added options install_ezmlm_mysql, vpopmail_mysql_repl_master_port,
        vpopmail_mysql_repl_slave_port

    t/Toaster.pm
        get_dir_files tests the file size to see if any domains are added
        yet (more reliable test)

    FreeBSD.pm
         fixed a recursion bug in ports_update (portsnap)
         install a default portsnap.conf if missing
         FreeBSD version detection wasn't working

    Apache.pm
         added security options to mail-toaster.conf to harden Apache
         added PHP AddType declarations
         added directory block for phpmyadmin
         only add phpmyadmin block if selected in toaster-watcher.conf

    Setup.pm
        ezmlm mysql support now depends on install_ezmlm_mysql setting
        instead of install_mysql.

        added support for vpopmail mysql database port number (thanks Erik!)

        vpopmail_mysql_database setting is now honored.

        busted huge vpopmail sub into a dozen smaller ones for easier
        maintenance.

        heredoc's used in creation of tcp.smtp used ' and needed "

        logic for NO_SENDMAIL test was inverted causing it to be added to
        /etc/make.conf more than once.

  5.02b - 2006.09.28
    index.cgi
        defined debug (caused it to not work)

    Apache.pm
        test for toaster_apache_vhost

        add alias for v-webmail, and roundcube to apache's vhost config
        file(mail-toaster.conf)

    Ezmlm.pm
         define any missing cgi params to suppress errors messages
         filled in pod description

    FreeBSD.pm - detection of portsdb wasn't working
        supress notification of new toaster-watcher.conf install if its
        missing

    Logs.pm - prettied up the yesterday report a little bit.
         added checks to prevent warnings when logs are empty
         log archiving was failing (invalid test)

    Perl.pm
         added pod doc for has_module

    Setup.pm
         phpmyadmin_install was not passing $conf

    Utility.pm
        Fixed a bug in mailtoaster sub that prevented it from finding the
        tw.conf file

        added _progress_??? subs for providing status messages on the CLI

        added pod documentation for several subs that had none

  5.01 - 2006.09.22
         added help->vpopmail option to web interface
         added setup -s allspam option (enabled mail filtering for all users)
         default ports update mechanism is now portsnap
         removed dependency on Net::DNS (using dig)

        commented out v-webmail, roundcube, vqadmin, and ezmlm menu options.
        Those items are not installed by Mail::Toaster (yet).

        added code in -s all target to refresh the $conf hashref after -s
        config target is run

        moved $conf into the Setup.pm object. Significantly reduced the
        amount of passing $conf around from sub to sub.

        added options and explicit port install options for gnupg and
        Archive::Tar to surpress dialog boxes.

        timer was not working in yes_or_no due to typo in param validation
        block

        disabled ezmlm and vqadmin in webmail. Activate them by removing the
        comments in mt-top.html

        default cvsup_supfile_sources settings is now cvsup-sources (was
        cvsup-stable)

        tweaks so "make test" runs with fewer warnings

        toaster_setup -s sources now auto-builds cvsup-sources if missing.
        The location for it is /usr/local/etc now.

  5.00 - 2006.09.18
    CODE QUALITY
        * Parameter validation for nearly all subroutines using
        Params::Validate. Backwards compatability is now destroyed, but that
        should not affect anyone as all published software that uses these
        functions is included with the distribution. Params::Validate is
        included in MT distribution.

        * Tests. Hundreds of new tests. In version 4, I added a plethora of
        tests, basically just making sure each sub and function would
        execute. Now most subs and functions have tests that verify inputs
        and results.

        * Switched to Test::More for tests. Provides more and better options
        for writing tests, comparing results, and figuring out where the
        tests failed.

        * Maillogs - a number of optimizations to make processing logs
        faster (shorter regexps, optimized ternaries to match common stuff
        first, removed POSIX requirement (lighten memory requirements),
        updated several of the counter functions to complain about unknown
        errors and values, more sanity checking in functions so they give up
        on errors instead of blithely charging ahead.

        * instead of eval's strewn all over to test for certain modules,
        added $perl->has_module

        * all objects are created with Class->new intead of new Class.

        * all errors raise exceptions by default. This requires callers to
        take specific action to change.

        * run tests early in subroutines, reduces giant if nests and makes
        it easier to read the code.

    MISC
        * Added Build.PL for use with Module::Build fans.

        * Greatly simplified Makefile.PL by moving "make cgi" and "make
        conf" logic into Setup.pm. Those functions are now accessed by
        toaster_setup targets.

        * OpenSSL config files are now updated automatically. Auto-generated
        certs now have the accurate information in them. Courier-IMAP certs
        are also updated automatically.

    DOCUMENTATION
        * Added three new test modules that test for: pod documentation for
        subs, pod formatting, and automatic checking of code to test for
        best practices.

        * moved POD documentation from being strewn about the files to the
        end of each file.

        * wrote and re-wrote significant portions of the documentation, as
        well as cleaned up formatting. Documentation is now easier to find
        as well.

         changed all tnpi.biz urls to tnpi.net
         shortened most tnpi.net urls to mail-toaster.org
         updated copyright notices to 2006
         moved usage() subs into pod docs and use pod2usage

    CODE FORMATTING & READABILITY
        * Used perltidy to format most of the source code.

        * Used perlcritic to identify and correct (almost) all instances
        where my code was not using best practices, as identified in Perl
        Best Practices.

        * All subroutines now take named arguments, making it easier to read
        the code and understand what is being sent and returned.

        * added "use English" pragma and replaced all the arcane $^ and $[
        perl variables with their english name equivalents.

    WEB INTERFACE/CGI
        * Completely new webmail/logon interface. Written entirely in HTML,
        CSS, and JavaScript.

        * The format of toaster-watcher.conf is altered slightly. It is more
        consistent in the internal layout so that my programs can alter it
        reliably.

        * removed httpd.conf patches in favor of installing a
        mail-toaster.conf file with all the requisite apache directives.

        * Organized all the cgi related docs into cgi_files directory. They
        are now installed via the -s webmail target to toaster_setup.
