NAME
       CPANPLUS::Dist::Base - Base class for custom distribution classes

SYNOPSIS
	   package CPANPLUS::Dist::MY_IMPLEMENTATION

	   use base 'CPANPLUS::Dist::Base';

	   sub prepare {
	       my $dist = shift;

	       ### do the 'standard' things
	       $dist->SUPER::prepare( @_ ) or return;

	       ### do MY_IMPLEMENTATION specific things
	       ...

	       ### don't forget to set the status!
	       return $dist->status->prepared( $SUCCESS ? 1 : 0 );
	   }

DESCRIPTION
       CPANPLUS::Dist::Base functions as a base class for all custom distribution
       implementations. It does all the mundane work CPANPLUS would have done without a custom
       distribution, so you can override just the parts you need to make your own implementation
       work.

FLOW
       Below is a brief outline when and in which order methods in this class are called:

	   $Class->format_available;   # can we use this class on this system?

	   $dist->init; 	       # set up custom accessors, etc
	   $dist->prepare;	       # find/write meta information
	   $dist->create;	       # write the distribution file
	   $dist->install;	       # install the distribution file

	   $dist->uninstall;	       # remove the distribution (OPTIONAL)

METHODS
   @subs = $Class->methods
       Returns a list of methods that this class implements that you can override.

   $bool = $Class->format_available
       This method is called when someone requests a module to be installed via the superclass.
       This gives you the opportunity to check if all the needed requirements to build and
       install this distribution have been met.

       For example, you might need a command line program, or a certain perl module installed to
       do your job. Now is the time to check.

       Simply return true if the request can proceed and false if it can not.

       The "CPANPLUS::Dist::Base" implementation always returns true.

   $bool = $dist->init
       This method is called just after the new dist object is set up and before the "prepare"
       method is called. This is the time to set up the object so it can be used with your class.

       For example, you might want to add extra accessors to the "status" object, which you might
       do as follows:

	   $dist->status->mk_accessors( qw[my_implementation_accessor] );

       The "status" object is implemented as an instance of the "Object::Accessor" class. Please
       refer to its documentation for details.

       Return true if the initialization was successful, and false if it was not.

       The "CPANPLUS::Dist::Base" implementation does not alter your object and always returns
       true.

   $bool = $dist->prepare
       This runs the preparation step of your distribution. This step is meant to set up the
       environment so the "create" step can create the actual distribution(file).  A "prepare"
       call in the standard "ExtUtils::MakeMaker" distribution would, for example, run "perl
       Makefile.PL" to find the dependencies for a distribution. For a "debian" distribution,
       this is where you would write all the metafiles required for the "dpkg-*" tools.

       The "CPANPLUS::Dist::Base" implementation simply calls the underlying distribution class
       (Typically "CPANPLUS::Dist::MM" or "CPANPLUS::Dist::Build").

       Sets "$dist->status->prepared" to the return value of this function.  If you override this
       method, you should make sure to set this value.

   $bool = $dist->create
       This runs the creation step of your distribution. This step is meant to follow up on the
       "prepare" call, that set up your environment so the "create" step can create the actual
       distribution(file).  A "create" call in the standard "ExtUtils::MakeMaker" distribution
       would, for example, run "make" and "make test" to build and test a distribution. For a
       "debian" distribution, this is where you would create the actual ".deb" file using "dpkg".

       The "CPANPLUS::Dist::Base" implementation simply calls the underlying distribution class
       (Typically "CPANPLUS::Dist::MM" or "CPANPLUS::Dist::Build").

       Sets "$dist->status->dist" to the location of the created distribution.	If you override
       this method, you should make sure to set this value.

       Sets "$dist->status->created" to the return value of this function.  If you override this
       method, you should make sure to set this value.

   $bool = $dist->install
       This runs the install step of your distribution. This step is meant to follow up on the
       "create" call, which prepared a distribution(file) to install.  A "create" call in the
       standard "ExtUtils::MakeMaker" distribution would, for example, run "make install" to copy
       the distribution files to their final destination. For a "debian" distribution, this is
       where you would run "dpkg --install" on the created ".deb" file.

       The "CPANPLUS::Dist::Base" implementation simply calls the underlying distribution class
       (Typically "CPANPLUS::Dist::MM" or "CPANPLUS::Dist::Build").

       Sets "$dist->status->installed" to the return value of this function.  If you override
       this method, you should make sure to set this value.

   $bool = $dist->uninstall
       This runs the uninstall step of your distribution. This step is meant to remove the
       distribution from the file system.  A "uninstall" call in the standard
       "ExtUtils::MakeMaker" distribution would, for example, run "make uninstall" to remove the
       distribution files the file system. For a "debian" distribution, this is where you would
       run "dpkg --uninstall PACKAGE".

       The "CPANPLUS::Dist::Base" implementation simply calls the underlying distribution class
       (Typically "CPANPLUS::Dist::MM" or "CPANPLUS::Dist::Build").

       Sets "$dist->status->uninstalled" to the return value of this function.	If you override
       this method, you should make sure to set this value.
