  $ perl -MCPAN -e 'install Apache2::WebApp'

Use of CPAN.pm in interactive mode:

  $ perl -MCPAN -e shell
  cpan> install Apache2::WebApp
  cpan> quit

Just like the manual installation of Perl modules, the user may need root access during
this process to insure write permission is allowed within the installation directory.

=head1 GETTING STARTED

=head2 HELPER SCRIPTS

=head3 Create a new project

  $ webapp-project --project_title Project --apache_doc_root /var/www

    or

  $ webapp-project --config /path/to/conf/webapp.conf

=head3 Export project settings to the Unix shell

  $ source /path/to/project/.projrc

=head3 Create a new class

  $ webapp-class --name ClassName

=head3 Add a pre-packaged I<Extra> to an existing project

  $ webapp-extra --install PackageName 

=head3 Start your application

  $ webapp-kickstart

=head3 Standard output

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

B) Base class that can be C<included> from other classes.  Contains C<_global()>
and C<_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 C<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 C<htpasswd> command-line script.

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

F) Apache server I<Virtual Host> configuration.

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

L) Temporary shared space for file processing.

=head1 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 C<webapp-kickstart>
script provided with this package.

=head1 WARNING

In Perl, variables do not need to be declared and are by default globally scoped.
The issue with I<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;
