=head1 NAME
is in turn depending on binary compatibility (so you cannot run CPAN
commands), then you should try the CPAN::Nox module for recovery.
+=head2 The 4 Classes: Authors, Bundles, Modules, Distributions
+
+Although it may be considered internal, the class hierarchie does
+matter for both users and programmer. CPAN.pm deals with above
+mentioned four classes, and all those classes share a set of
+methods. It is a classical single polymorphism that is in effect. A
+metaclass object registers all objects of all kinds and indexes them
+with a string. The strings referencing objects have a separated
+namespace (well, not completely separated):
+
+ Namespace Class
+
+ words containing a "/" (slash) Distribution
+ words starting with Bundle:: Bundle
+ everything else Module or Author
+
+Modules know their associated Distribution objects. They always refer
+to the most recent official release. Developers may mark their
+releases as unstable development versions (by inserting an underbar
+into the visible version number), so not always is the default
+distribution for a given module the really hottest and newest. If a
+module Foo circulates on CPAN in both version 1.23 and 1.23_90,
+CPAN.pm offers a convenient way to install version 1.23 by saying
+
+ install Foo
+
+This would install the complete distribution file (say
+BAR/Foo-1.23.tar.gz) with all accompanying material in there. But if
+you would like to install version 1.23_90, you need to know where the
+distribution file resides on CPAN relative to the authors/id/
+directory. If the author is BAR, this might be BAR/Foo-1.23_90.tar.gz,
+so he would have say
+
+ install BAR/Foo-1.23_90.tar.gz
+
+The first example will be driven by an object of the class
+CPAN::Module, the second by an object of class Distribution.
+
=head2 ProgrammerE<39>s interface
If you do not enter the shell, the available shell commands are both
available as methods (C<CPAN::Shell-E<gt>install(...)>) and as
-functions in the calling package (C<install(...)>). The
-programmerE<39>s interface has beta status. Do not heavily rely on it,
-changes may still be necessary.
+functions in the calling package (C<install(...)>).
+
+There's currently only one class that has a stable interface,
+CPAN::Shell. All commands that are available in the CPAN shell are
+methods of the class CPAN::Shell. The commands that produce listings
+of modules (C<r>, C<autobundle>, C<u>) return a list of the IDs of all
+modules within the list.
+
+=over 2
+
+=item expand($type,@things)
+
+The IDs of all objects available within a program are strings that can
+be expanded to the corresponding real objects with the
+C<CPAN::Shell-E<gt>expand()> method. Expand returns a list of
+CPAN::Module objects according to the C<@things> arguments given. In
+scalar context it only returns the first element of the list.
+
+=item Programming Examples
+
+This enables the programmer to do operations like these:
+
+ # install everything that is outdated on my disk:
+ perl -MCPAN -e 'CPAN::Shell->install(CPAN::Shell->r)'
+
+ # install my favorite programs if necessary:
+ for $mod (qw(Net::FTP MD5 Data::Dumper)){
+ my $obj = CPAN::Shell->expand('Module',$mod);
+ $obj->install;
+ }
