NAME
    Wala.pm - easy minimalist wiki

SYNOPSIS
    As a standalone wiki app:

        #!/usr/bin/perl
        use Wala;
        my $w = Wala->new;
        $w->run;

    Pulling content into other scripts:

        $text = $w->print_page('SandBox');

DESCRIPTION
    This is a Wala, which is a derivation of a wiki that incorporates
    appending text directly to pages, turning a wiki into something more
    like a forum while retaining all the wonderful full-page editing
    features of a wiki.

INSTALLATION
    This script is a self-contained package, which makes the code easy to
    test. To actually use it as a wala, create a script named "wala.pl" in
    the same directory, containing the following three lines:

        #!/usr/bin/perl
        use Wala;
        my $w = Wala->new();
        $w->run;

    You can experiment with the wala by use'ing it and calling its functions
    without calling "run". By default, required directories and files should
    be created as needed, but you can visit wala.pl?setup in your browser,
    or call "setup()" from a script at any time.

  CONFIGURATION
    You can set options directly from the calling script, like so:

        #!/usr/bin/perl
        use Wala;

        my $w = Wala->new(
            RecentChangesMaxLines => 50,  # Max lines to display in RecentChanges
            DefaultUserName       => 'Anonymous',  # Default user name
            StyleSheet            => 'wala.css',  # URL of style sheet
            DefaultPageText       => "Write something.\n",
            CookieSurvivalDays    => 90,  # Number of days for cookies to remain
            RootDir               => '.', # No trailing slash, please
            HomePage              => 'HomePage', # Name of default page
            TimeZone              => 'UTC', # Currently just a string to display
            TitleString           => 'wala::', # Display before page names in titles
            ScriptName            => 'wala.pl',
            ShowSearchlinks       => 1, # Display "see also" box on pages
            LogRelatedLinks       => 1, # Log related links for a given change.
            CheckSetup            => 1, # Check for setup files every time
            UseCache              => 0, # Don't use caching behavior
        );

        $w->run;

  FEEDS
    Feeds are practically a requirement these days. While it wouldn't be the
    hardest thing in the world to roll my own Atom or RSS within Wala.pm, it
    was much less painful to look to CPAN, which offers
    XML::Atom::SimpleFeed.

    I've included a simple wala_feed.pl, which relies on the aforementioned
    module. It shouldn't be too hard to customize.

    If you do something along the lines of:

        FeedURL => 'http://p1k3.com/wala/wala_feed.pl',

    in your configuration, Wala.pm will link to your feed in page headers so
    that browsers like Firefox will auto-discover it.
