+
+These two commands take only one argument, be it a module or a

+appropriate directory and opens a subshell process in that directory.
+
+=item Signals
+
+CPAN.pm installs signal handlers for SIGINT and SIGTERM. While you are
+in the cpan-shell it is intended that you can press C<^C> anytime and
+return to the cpan-shell prompt. A SIGTERM will cause the cpan-shell
+to clean up and leave the shell loop. You can emulate the effect of a
+SIGTERM by sending two consecutive SIGINTs, which usually means by
+pressing C<^C> twice.
+
+CPAN.pm ignores a SIGPIPE. If the user sets inactivity_timeout, a
+SIGALRM is used during the run of the C<perl Makefile.PL> subprocess.

+
+=head2 autobundle
+
+C<autobundle> writes a bundle file into the
+C<$CPAN::Config-E<gt>{cpan_home}/Bundle> directory. The file contains
+a list of all modules that are both available from CPAN and currently
+installed within @INC. The name of the bundle file is based on the
+current date and a counter.
+
+=head2 recompile
+
+recompile() is a very special command in that it takes no argument and
+runs the make/test/install cycle with brute force over all installed
+dynamically loadable extensions (aka XS modules) with 'force' in
+effect. The primary purpose of this command is to finish a network
+installation. Imagine, you have a common source tree for two different
+architectures. You decide to do a completely independent fresh
+installation. You start on one architecture with the help of a Bundle
+file produced earlier. CPAN installs the whole Bundle for you, but
+when you try to repeat the job on the second architecture, CPAN
+responds with a C<"Foo up to date"> message for all modules. So you
+invoke CPAN's recompile on the second architecture and youE<39>re done.
+
+Another popular use for C<recompile> is to act as a rescue in case your
+perl breaks binary compatibility. If one of the modules that CPAN uses
+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 four C<CPAN::*> Classes: Author, Bundle, Module, Distribution
+
+Although it may be considered internal, the class hierarchy does matter
+for both users and programmer. CPAN.pm deals with above mentioned four
+classes, and all those classes share a set of methods. A classical
+single polymorphism 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 the really hottest and newest distribution
+file is not always the default. 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. 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 you would have to 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 CPAN::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. Each of the commands that produce
+listings of modules (C<r>, C<autobundle>, C<u>) returns 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("Module",@things)> 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 that combine
+functionalities that are available in the shell.

+ perl -MCPAN -e 'CPAN::Shell->install(CPAN::Shell->r)'

+ # install my favorite programs if necessary:

=head2 Cache Manager

variable. After that the pod section looks like any other pod with the

-(eg. Foo::Bar, ie. I<not> the name of the distribution file). The rest
+(e.g. Foo::Bar, ie. I<not> the name of the distribution file). The rest
of the line is optional. The comment part is delimited by a dash just
as in the man page header.
Bundles are treated specially in the CPAN package. If you say 'install
Bundle::Tkkit' (assuming such a bundle exists), CPAN will install all
-the modules in the CONTENTS section of the pod. You can install your
+the modules in the CONTENTS section of the pod. You can install your
own Bundles locally by placing a conformant Bundle file somewhere into
your @INC path. The autobundle() command which is available in the
shell interface does that for you by including all currently installed
modules in a snapshot bundle file.
-There is a meaningless Bundle::Demo available on CPAN. Try to install
-it, it usually does no harm, just demonstrates what the Bundle
-interface looks like.

+associated with an URL that is not C<ftp:>.
-C<autobundle> writes a bundle file into the
-C<$CPAN::Config-E<gt>{cpan_home}/Bundle> directory. The file contains
-a list of all modules that are both available from CPAN and currently
-installed within @INC. The name of the bundle file is based on the
-current date and a counter.

-=head2 recompile

+
+=head2 Floppy, Zip, and all that Jazz
+
+CPAN.pm works nicely without network too. If you maintain machines
+that are not networked at all, you should consider working with file:
+URLs. Of course, you have to collect your modules somewhere first. So
+you might use CPAN.pm to put together all you need on a networked
+machine. Then copy the $CPAN::Config->{keep_source_where} (but not
+$CPAN::Config->{build_dir}) directory on a floppy. This floppy is kind
+of a personal CPAN. CPAN.pm on the non-networked machines works nicely
+with this floppy.

+=head2 CD-ROM support
+
+The C<urllist> parameter of the configuration table contains a list of
+URLs that are to be used for downloading. If the list contains any
+C<file> URLs, CPAN always tries to get files from there first. This
+feature is disabled for index files. So the recommendation for the
+owner of a CD-ROM with CPAN contents is: include your local, possibly
+outdated CD-ROM as a C<file> URL at the end of urllist, e.g.
+
+ o conf urllist push file://localhost/CDROM/CPAN
+
+CPAN.pm will then fetch the index files from one of the CPAN sites
+that come at the beginning of urllist. It will later check for each
+module if there is a local copy of the most recent version.

=head1 SECURITY
There's no strong security layer in CPAN.pm. CPAN.pm helps you to
for this is that the primary use is intended for the cpan shell or for
oneliners.
