    A) Application directory. All classes *(*.pm)* within this directory are
    precompiled into memory when Apache starts/restarts.

    B) Base class that can be "included" from other classes. Contains
    "_global()" and "_error()" methods that can be inherited using:

    Example:

      use base 'Project::Base';

    C) Basic class.

    D) This is executed when the Apache server starts. It's used to reset
    Perl module search paths in @INC, preload web application classes,
    precompile constants, etc.

    Example:

      #!/usr/bin/env perl

      $ENV{MOD_PERL} or die "Not running under mod_perl";

      use lib '/var/www/project/app';

      ..

      # Modules added here will be URI accessible 
      __DATA__ 
      Project::Foo
      Project::Foo::Bar

    E) Password file used for restricting access to a specified path (see
    "httpd.conf").

    The login information below is currently set-up by default.

      User Name       admin
      Password        password

    You can change the login password using the "htpasswd" command-line
    script.

      $ htpasswd /var/www/project/conf/htpasswd admin

    F) Apache server *Virtual Host* configuration.

    G) Application configuration. This file contains your project settings.
    Due to security reasons, this file should always remain outside the
    */htdocs* directory path.

    Example:

      [project]
      title              = Project                                 # must not contain spaces or special characters
      author             = Your Name Here
      email              = email@domain.com
      version            = 0.01

      [apache]
      doc_root           = /var/www/project                        # path to project directory
      domain             = www.domain.com                          # valid domain name
      disable_uploads    = 0                                       # allow file uploads
      post_max           = 5242880                                 # post max in bytes (example 5MB)
      temp_dir           = /var/www/project/tmp/uploads

      [template]
      cache_size         = 100                                     # total files to store in cache
      compile_dir        = /var/www/project/tmp/cache/templates    # path to template cache
      include_path       = /var/www/project/templates              # path to template directory
      stat_ttl           = 60                                      # template to HTML build time (in seconds)
      encoding           = utf8                                    # template output encoding

    H) Website sources. This includes HTML, CSS, Javascript, and images.
    When setting up FTP access - restrict access to this directory only.

    I) Basic template.

    J) Application error templates.

    K) Apache log directory that contains both access and error logs. Due to
    security reasons, this directory should always remain outside the
    */htdocs* directory path.

    L) Temporary shared space for file processing.

CAVEATS
    Since your classes get compiled at Apache start-up the server must be
    restarted when any code changes take place. You can do this easily using
    the "webapp-kickstart" script provided with this package.

WARNING
    In Perl, variables do not need to be declared and are by default
    globally scoped. The issue with *mod_perl* is that global variables can
    persist between requests. To avoid this problem, you should always have
    the following line in your code:

      use strict;
