-download clients) to fetch the raw data from the net.
+The CPAN module automates or at least simplifies the make and install
+of perl modules and extensions. It includes some primitive searching
+capabilities and knows how to use Net::FTP or LWP or some external
+download clients to fetch the distributions from the net.
-Distributions are fetched from one or more of the mirrored CPAN
-(Comprehensive Perl Archive Network) sites and unpacked in a dedicated
-directory.
+These are fetched from one or more of the mirrored CPAN (Comprehensive
+Perl Archive Network) sites and unpacked in a dedicated directory.
The CPAN module also supports the concept of named and versioned
I<bundles> of modules. Bundles simplify the handling of sets of

-=head1 PROGRAMMER'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(...)>). Before calling low-level
-commands it makes sense to initialize components of CPAN you need, e.g.:
-
- CPAN::HandleConfig->load;
- CPAN::Shell::setup_output;
- CPAN::Index->reload;
-
-High-level commands do such initializations automatically.
-
-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>) also 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("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 expandany(@things)
-
-Like expand, but returns objects of the appropriate type, i.e.
-CPAN::Bundle objects for bundles, CPAN::Module objects for modules and
-CPAN::Distribution objects for distributions. Note: it does not expand
-to CPAN::Author objects.
-
-=item Programming Examples
-
-This enables the programmer to do operations that combine
-functionalities that are available in the shell.
-
- # install everything that is outdated on my disk:
- perl -MCPAN -e 'CPAN::Shell->install(CPAN::Shell->r)'
-
- # install my favorite programs if necessary:
- for $mod (qw(Net::FTP Digest::SHA Data::Dumper)){
- CPAN::Shell->install($mod);
- }
-
- # list all modules on my disk that have no VERSION number
- for $mod (CPAN::Shell->expand("Module","/./")){
- next unless $mod->inst_file;
- # MakeMaker convention for undefined $VERSION:
- next unless $mod->inst_version eq "undef";
- print "No VERSION in ", $mod->id, "\n";
- }
-
- # find out which distribution on CPAN contains a module:
- print CPAN::Shell->expand("Module","Apache::Constants")->cpan_file
-
-Or if you want to write a cronjob to watch The CPAN, you could list
-all modules that need updating. First a quick and dirty way:
-
- perl -e 'use CPAN; CPAN::Shell->r;'
-
-If you don't want to get any output in the case that all modules are
-up to date, you can parse the output of above command for the regular
-expression //modules are up to date// and decide to mail the output
-only if it doesn't match. Ick?
-
-If you prefer to do it more in a programmer style in one single
-process, maybe something like this suits you better:
-
- # list all modules on my disk that have newer versions on CPAN
- for $mod (CPAN::Shell->expand("Module","/./")){
- next unless $mod->inst_file;
- next if $mod->uptodate;
- printf "Module %s is installed as %s, could be updated to %s from CPAN\n",
- $mod->id, $mod->inst_version, $mod->cpan_version;
- }
-
-If that gives you too much output every day, you maybe only want to
-watch for three modules. You can write
-
- for $mod (CPAN::Shell->expand("Module","/Apache|LWP|CGI/")){
-
-as the first line instead. Or you can combine some of the above
-tricks:
+=head1 CONFIGURATION
- # watch only for a new mod_perl module
- $mod = CPAN::Shell->expand("Module","mod_perl");
- exit if $mod->uptodate;
- # new mod_perl arrived, let me know all update recommendations
- CPAN::Shell->r;
+When the CPAN module is used for the first time, a configuration
+dialog tries to determine a couple of site specific options. The
+result of the dialog is stored in a hash reference C< $CPAN::Config >
+in a file CPAN/Config.pm.
-=back
+The default values defined in the CPAN/Config.pm file can be
+overridden in a user specific file: CPAN/MyConfig.pm. Such a file is
+best placed in $HOME/.cpan/CPAN/MyConfig.pm, because $HOME/.cpan is
+added to the search path of the CPAN module before the use() or
+require() statements. The mkmyconfig command writes this file for you.

+=item completion support
-Returns a one-line description of the author
+If you have a ReadLine module installed, you can hit TAB at any point

+=item displaying some help: o conf help
-Returns a multi-line description of the author
+Displays a short help
-=item CPAN::Author::email()
+=item displaying current values: o conf [KEY]
-Returns the author's email address
+Displays the current value(s) for this config variable. Without KEY

-=item CPAN::Bundle::as_glimpse()
+Example:
-Returns a one-line description of the bundle
+ o conf wget /usr/bin/wget
-=item CPAN::Bundle::as_string()
+=item changing of list values: o conf KEY SHIFT|UNSHIFT|PUSH|POP|SPLICE|LIST
-Returns a multi-line description of the bundle
+If a config variable name ends with C<list>, it is a list. C<o conf
+KEY shift> removes the first element of the list, C<o conf KEY pop>
+removes the last element of the list. C<o conf KEYS unshift LIST>
+prepends a list of values to the list, C<o conf KEYS push LIST>
+appends a list of valued to the list.
-=item CPAN::Bundle::clean()
+Likewise, C<o conf KEY splice LIST> passes the LIST to the according
+splice command.
-Recursively runs the C<clean> method on all items contained in the bundle.
+Finally, any other list of arguments is taken as a new list value for
+the KEY variable discarding the previous value.
-=item CPAN::Bundle::contains()
+Examples:
-Returns a list of objects' IDs contained in a bundle. The associated

+=item reverting to saved: o conf defaults
-Forces CPAN to perform a task that it normally would have refused to
-do. Force takes as arguments a method name to be called and any number
-of additional arguments that should be passed to the called method.
-The internals of the object get the needed changes so that CPAN.pm
-does not refuse to take the action. The C<force> is passed recursively
-to all contained objects. See also the section above on the C<force>

+Saves all config variables to the current config file (CPAN/Config.pm
+or CPAN/MyConfig.pm that was loaded at start).
-=item CPAN::Bundle::inst_file()
+=back
-Returns the highest installed version of the bundle in either @INC or
-C<$CPAN::Config->{cpan_home}>. Note that this is different from
-CPAN::Module::inst_file.
+The configuration dialog can be started any time later again by
+issuing the command C< o conf init > in the CPAN shell. A subset of
+the configuration dialog can be run by issuing C<o conf init WORD>
+where WORD is any valid config variable or a regular expression.

+=item backtickcwd

+Calls the external command cwd.
+
+=back
+
+=head2 Note on the format of the urllist parameter
+
+urllist parameters are URLs according to RFC 1738. We do a little
+guessing if your URL is not compliant, but if you have problems with
+C<file> URLs, please try the correct format. Either:
+
+ file://localhost/whatever/ftp/pub/CPAN/
+
+or
+
+ file:///home/ftp/pub/CPAN/
+
+=head2 The urllist parameter has 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.
+
+Another peculiarity of urllist is that the site that we could
+successfully fetch the last file from automatically gets a preference
+token and is tried as the first site for the next request. So if you
+add a new site at runtime it may happen that the previously preferred
+site will be tried another time. This means that if you want to disallow
+a site for the next transfer, it must be explicitly removed from
+urllist.
+
+=head2 Maintaining the urllist parameter
+
+If you have YAML.pm (or some other YAML module configured in
+C<yaml_module>) installed, CPAN.pm collects a few statistical data
+about recent downloads. You can view the statistics with the C<hosts>
+command or inspect them directly by looking into the C<FTPstats.yml>
+file in your C<cpan_home> directory.
+
+To get some interesting statistics it is recommended to set the
+C<randomize_urllist> parameter that introduces some amount of
+randomness into the URL selection.
+
+=head2 The C<requires> and C<build_requires> dependency declarations
+
+Since CPAN.pm version 1.88_51 modules declared as C<build_requires> by
+a distribution are treated differently depending on the config
+variable C<build_requires_install_policy>. By setting
+C<build_requires_install_policy> to C<no> such a module is not being
+installed. It is only built and tested and then kept in the list of
+tested but uninstalled modules. As such it is available during the
+build of the dependent module by integrating the path to the
+C<blib/arch> and C<blib/lib> directories in the environment variable
+PERL5LIB. If C<build_requires_install_policy> is set ti C<yes>, then
+both modules declared as C<requires> and those declared as
+C<build_requires> are treated alike. By setting to C<ask/yes> or
+C<ask/no>, CPAN.pm asks the user and sets the default accordingly.
+
+=head2 Configuration for individual distributions (I<Distroprefs>)
+
+(B<Note:> This feature has been introduced in CPAN.pm 1.8854 and is
+still considered beta quality)
+
+Distributions on the CPAN usually behave according to what we call the
+CPAN mantra. Or since the event of Module::Build we should talk about
+two mantras:
+
+ perl Makefile.PL perl Build.PL
+ make ./Build
+ make test ./Build test
+ make install ./Build install
+
+But some modules cannot be built with this mantra. They try to get
+some extra data from the user via the environment, extra arguments or
+interactively thus disturbing the installation of large bundles like
+Phalanx100 or modules with many dependencies like Plagger.
+
+The distroprefs system of C<CPAN.pm> addresses this problem by
+allowing the user to specify extra informations and recipes in YAML
+files to either
+
+=over
+
+=item
+
+pass additional arguments to one of the four commands,
+
+=item
+
+set environment variables
+
+=item
+
+instantiate an Expect object that reads from the console, waits for
+some regular expressions and enters some answers
+
+=item
+
+temporarily override assorted C<CPAN.pm> configuration variables
+
+=item
+
+disable the installation of an object altogether
+
+=back
+
+See the YAML and Data::Dumper files that come with the C<CPAN.pm>
+distribution in the C<distroprefs/> directory for examples.
+
+=head2 Filenames
+
+The YAML files themselves must have the C<.yml> extension, all other
+files are ignored (for two exceptions see I<Fallback Data::Dumper and
+Storable> below). The containing directory can be specified in
+C<CPAN.pm> in the C<prefs_dir> config variable. Try C<o conf init
+prefs_dir> in the CPAN shell to set and activate the distroprefs
+system.
+
+Every YAML file may contain arbitrary documents according to the YAML
+specification and every single document is treated as an entity that
+can specify the treatment of a single distribution.
+
+The names of the files can be picked freely, C<CPAN.pm> always reads
+all files (in alphabetical order) and takes the key C<match> (see
+below in I<Language Specs>) as a hashref containing match criteria
+that determine if the current distribution matches the YAML document
+or not.
+
+=head2 Fallback Data::Dumper and Storable
+
+If neither your configured C<yaml_module> nor YAML.pm is installed
+CPAN.pm falls back to using Data::Dumper and Storable and looks for
+files with the extensions C<.dd> or C<.st> in the C<prefs_dir>
+directory. These files are expected to contain one or more hashrefs.
+For Data::Dumper generated files, this is expected to be done with by
+defining C<$VAR1>, C<$VAR2>, etc. The YAML shell would produce these
+with the command
+
+ ysh < somefile.yml > somefile.dd
+
+For Storable files the rule is that they must be constructed such that
+C<Storable::retrieve(file)> returns an array reference and the array
+elements represent one distropref object each. The conversion from
+YAML would look like so:
+
+ perl -MYAML=LoadFile -MStorable=nstore -e '
+ @y=LoadFile(shift);
+ nstore(\@y, shift)' somefile.yml somefile.st
+
+In bootstrapping situations it is usually sufficient to translate only
+a few YAML files to Data::Dumper for the crucial modules like
+C<YAML::Syck>, C<YAML.pm> and C<Expect.pm>. If you prefer Storable
+over Data::Dumper, remember to pull out a Storable version that writes
+an older format than all the other Storable versions that will need to
+read them.

+
+=item eexpect [hash]
+
+Extended C<expect>. This is a hash reference with three allowed keys,
+C<mode>, C<timeout>, and C<talk>.
+
+C<mode> may have the values C<deterministic> for the case where all
+questions come in the order written down and C<anyorder> for the case
+where the questions may come in any order. The default mode is
+C<deterministic>.
+
+C<timeout> denotes a timeout in seconds. Floating point timeouts are
+OK. In the case of a C<mode=deterministic> the timeout denotes the
+timeout per question, in the case of C<mode=anyorder> it denotes the
+timeout per byte received from the stream or questions.
+
+C<talk> is a reference to an array that contains alternating questions
+and answers. Questions are regular expressions and answers are literal
+strings. The Expect module will then watch the stream coming from the
+execution of the external program (C<perl Makefile.PL>, C<perl
+Build.PL>, C<make>, etc.).
+
+In the case of C<mode=deterministic> the CPAN.pm will inject the
+according answer as soon as the stream matches the regular expression.
+In the case of C<mode=anyorder> the CPAN.pm will answer a question as
+soon as the timeout is reached for the next byte in the input stream.
+In the latter case it removes the according question/answer pair from
+the array, so if you want to answer the question C<Do you really want
+to do that> several times, then it must be included in the array at
+least as often as you want this answer to be given.
+
+=item env [hash]
+
+Environment variables to be set during the command
+
+=item expect [array]
+
+C<< expect: <array> >> is a short notation for
+
+ eexpect:

+=head2 Schema verification with C<Kwalify>
+
+If you have the C<Kwalify> module installed (which is part of the
+Bundle::CPANxxl), then all your distroprefs files are checked for
+syntactical correctness.
+
+=head2 Example Distroprefs Files
+
+C<CPAN.pm> comes with a collection of example YAML files. Note that these
+are really just examples and should not be used without care because
+they cannot fit everybody's purpose. After all the authors of the
+packages that ask questions had a need to ask, so you should watch
+their questions and adjust the examples to your environment and your
+needs. You have beend warned:-)
+
+=head1 PROGRAMMER'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(...)>). Before calling low-level
+commands it makes sense to initialize components of CPAN you need, e.g.:
+
+ CPAN::HandleConfig->load;
+ CPAN::Shell::setup_output;
+ CPAN::Index->reload;
+
+High-level commands do such initializations automatically.
+
+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>) also 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("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 expandany(@things)
+
+Like expand, but returns objects of the appropriate type, i.e.
+CPAN::Bundle objects for bundles, CPAN::Module objects for modules and
+CPAN::Distribution objects for distributions. Note: it does not expand
+to CPAN::Author objects.
+
+=item Programming Examples
+
+This enables the programmer to do operations that combine
+functionalities that are available in the shell.
+
+ # install everything that is outdated on my disk:
+ perl -MCPAN -e 'CPAN::Shell->install(CPAN::Shell->r)'
+
+ # install my favorite programs if necessary:
+ for $mod (qw(Net::FTP Digest::SHA Data::Dumper)){
+ CPAN::Shell->install($mod);
+ }
+
+ # list all modules on my disk that have no VERSION number
+ for $mod (CPAN::Shell->expand("Module","/./")){
+ next unless $mod->inst_file;
+ # MakeMaker convention for undefined $VERSION:
+ next unless $mod->inst_version eq "undef";
+ print "No VERSION in ", $mod->id, "\n";
+ }
+
+ # find out which distribution on CPAN contains a module:
+ print CPAN::Shell->expand("Module","Apache::Constants")->cpan_file
+
+Or if you want to write a cronjob to watch The CPAN, you could list
+all modules that need updating. First a quick and dirty way:
+
+ perl -e 'use CPAN; CPAN::Shell->r;'
+
+If you don't want to get any output in the case that all modules are
+up to date, you can parse the output of above command for the regular
+expression //modules are up to date// and decide to mail the output
+only if it doesn't match. Ick?
+
+If you prefer to do it more in a programmer style in one single
+process, maybe something like this suits you better:
+
+ # list all modules on my disk that have newer versions on CPAN
+ for $mod (CPAN::Shell->expand("Module","/./")){
+ next unless $mod->inst_file;
+ next if $mod->uptodate;
+ printf "Module %s is installed as %s, could be updated to %s from CPAN\n",
+ $mod->id, $mod->inst_version, $mod->cpan_version;
+ }
+
+If that gives you too much output every day, you maybe only want to
+watch for three modules. You can write
+
+ for $mod (CPAN::Shell->expand("Module","/Apache|LWP|CGI/")){
+
+as the first line instead. Or you can combine some of the above
+tricks:
+
+ # watch only for a new mod_perl module
+ $mod = CPAN::Shell->expand("Module","mod_perl");
+ exit if $mod->uptodate;
+ # new mod_perl arrived, let me know all update recommendations
+ CPAN::Shell->r;

In this pod section each line obeys the format
- Module_Name [Version_String] [- optional text]
-
-The only required part is the first field, the name of a module
-(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.
-
-The distribution of a bundle should follow the same convention as
-other distributions.
-
-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
-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.
-
-=head1 PREREQUISITES
-
-If you have a local mirror of CPAN and can access all files with
-"file:" URLs, then you only need a perl better than perl5.003 to run
-this module. Otherwise Net::FTP is strongly recommended. LWP may be
-required for non-UNIX systems or if your nearest CPAN site is
-associated with a URL that is not C<ftp:>.
-
-If you have neither Net::FTP nor LWP, there is a fallback mechanism
-implemented for an external ftp command or for an external lynx
-command.

-This module presumes that all packages on CPAN

-
-=item *
-
-declare their $VERSION variable in an easy to parse manner. This
-prerequisite can hardly be relaxed because it consumes far too much
-memory to load all packages into the running program just to determine
-the $VERSION variable. Currently all programs that are dealing with
-version use something like this
-
- perl -MExtUtils::MakeMaker -le \
- 'print MM->parse_version(shift)' filename
-
-If you are author of a package and wonder if your $VERSION can be
-parsed, please try the above method.
-
-=item *
-
-come as compressed or gzipped tarfiles or as zip files and contain a
-C<Makefile.PL> or C<Build.PL> (well, we try to handle a bit more, but
-without much enthusiasm).
-
-=back
-
-=head2 Debugging
-
-The debugging of this module is a bit complex, because we have
-interferences of the software producing the indices on CPAN, of the
-mirroring process on CPAN, of packaging, of configuration, of
-synchronicity, and of bugs within CPAN.pm.
-
-For debugging the code of CPAN.pm itself in interactive mode some more
-or less useful debugging aid can be turned on for most packages within
-CPAN.pm with one of
-
-=over 2
-
-=item o debug package...

-sets debug mode for packages.
-
-=item o debug -package...
-
-unsets debug mode for packages.
-
-=item o debug all
-
-turns debugging on for all packages.
-
-=item o debug number
-
-=back
-
-which sets the debugging packages directly. Note that C<o debug 0>
-turns debugging off.
-
-What seems quite a successful strategy is the combination of C<reload
-cpan> and the debugging switches. Add a new debug statement while
-running in the shell and then issue a C<reload cpan> and see the new
-debugging messages immediately without losing the current context.
-
-C<o debug> without an argument lists the valid package names and the
-current set of packages in debugging mode. C<o debug> has built-in
-completion support.
-
-For debugging of CPAN data there is the C<dump> command which takes
-the same arguments as make/test/install and outputs each object's
-Data::Dumper dump. If an argument looks like a perl variable and
-contains one of C<$>, C<@> or C<%>, it is eval()ed and fed to
-Data::Dumper directly.
-
-=head2 Floppy, Zip, Offline Mode
-
-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. See also below the paragraph about CD-ROM support.

-=head2 Basic Utilities for Programmers
-
-=over 2
-
-=item has_inst($module)
-
-Returns true if the module is installed. Used to load all modules into
-the running CPAN.pm which are considered optional. The config variable
-C<dontload_list> can be used to intercept the C<has_inst()> call such
-that an optional module is not loaded despite being available. For
-example the following command will prevent that C<YAML.pm> is being
-loaded:
-
- cpan> o conf dontload_list push YAML
-
-See the source for details.
-
-=item has_usable($module)
-
-Returns true if the module is installed and is in a usable state. Only
-useful for a handful of modules that are used internally. See the
-source for details.
-
-=item instance($module)
-
-The constructor for all the singletons used to represent modules,
-distributions, authors and bundles. If the object already exists, this
-method returns the object, otherwise it calls the constructor.
-
-=back
-
-=head1 CONFIGURATION
-
-When the CPAN module is used for the first time, a configuration
-dialog tries to determine a couple of site specific options. The
-result of the dialog is stored in a hash reference C< $CPAN::Config >
-in a file CPAN/Config.pm.
-
-The default values defined in the CPAN/Config.pm file can be
-overridden in a user specific file: CPAN/MyConfig.pm. Such a file is
-best placed in $HOME/.cpan/CPAN/MyConfig.pm, because $HOME/.cpan is
-added to the search path of the CPAN module before the use() or
-require() statements. The mkmyconfig command writes this file for you.
-
-The C<o conf> command has various bells and whistles:
-
-=over
-
-=item completion support
-
-If you have a ReadLine module installed, you can hit TAB at any point
-of the commandline and C<o conf> will offer you completion for the
-built-in subcommands and/or config variable names.
-
-=item displaying some help: o conf help
-
-Displays a short help
-
-=item displaying current values: o conf [KEY]
-
-Displays the current value(s) for this config variable. Without KEY
-displays all subcommands and config variables.
-
-Example:
-
- o conf shell
-
-=item changing of scalar values: o conf KEY VALUE
-
-Sets the config variable KEY to VALUE. The empty string can be
-specified as usual in shells, with C<''> or C<"">
-
-Example:
-
- o conf wget /usr/bin/wget
-
-=item changing of list values: o conf KEY SHIFT|UNSHIFT|PUSH|POP|SPLICE|LIST
-
-If a config variable name ends with C<list>, it is a list. C<o conf
-KEY shift> removes the first element of the list, C<o conf KEY pop>
-removes the last element of the list. C<o conf KEYS unshift LIST>
-prepends a list of values to the list, C<o conf KEYS push LIST>
-appends a list of valued to the list.
-
-Likewise, C<o conf KEY splice LIST> passes the LIST to the according
-splice command.
-
-Finally, any other list of arguments is taken as a new list value for
-the KEY variable discarding the previous value.
-
-Examples:
-
- o conf urllist unshift http://cpan.dev.local/CPAN
- o conf urllist splice 3 1
- o conf urllist http://cpan1.local http://cpan2.local ftp://ftp.perl.org
-
-=item interactive editing: o conf init [MATCH|LIST]
-
-Runs an interactive configuration dialog for matching variables.
-Without argument runs the dialog over all supported config variables.
-To specify a MATCH the argument must be enclosed by slashes.
-
-Examples:
-
- o conf init ftp_passive ftp_proxy
- o conf init /color/
-
-=item reverting to saved: o conf defaults
-
-Reverts all config variables to the state in the saved config file.
-
-=item saving the config: o conf commit
-
-Saves all config variables to the current config file (CPAN/Config.pm
-or CPAN/MyConfig.pm that was loaded at start).
-
-=back
-
-The configuration dialog can be started any time later again by
-issuing the command C< o conf init > in the CPAN shell. A subset of
-the configuration dialog can be run by issuing C<o conf init WORD>
-where WORD is any valid config variable or a regular expression.

-urllist parameters are URLs according to RFC 1738. We do a little
-guessing if your URL is not compliant, but if you have problems with
-C<file> URLs, please try the correct format. Either:
+What seems quite a successful strategy is the combination of C<reload

+C<o debug> without an argument lists the valid package names and the
+current set of packages in debugging mode. C<o debug> has built-in
+completion support.

+For debugging of CPAN data there is the C<dump> command which takes
+the same arguments as make/test/install and outputs each object's
+Data::Dumper dump. If an argument looks like a perl variable and
+contains one of C<$>, C<@> or C<%>, it is eval()ed and fed to
+Data::Dumper directly.

+=head2 Floppy, Zip, Offline Mode
-=head2 urllist parameter has CD-ROM support
+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. See also below the paragraph about 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.
+=head2 Basic Utilities for Programmers
- o conf urllist push file://localhost/CDROM/CPAN
+=over 2
-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.
+=item has_inst($module)
-Another peculiarity of urllist is that the site that we could
-successfully fetch the last file from automatically gets a preference
-token and is tried as the first site for the next request. So if you
-add a new site at runtime it may happen that the previously preferred
-site will be tried another time. This means that if you want to disallow
-a site for the next transfer, it must be explicitly removed from
-urllist.
+Returns true if the module is installed. Used to load all modules into
+the running CPAN.pm which are considered optional. The config variable
+C<dontload_list> can be used to intercept the C<has_inst()> call such
+that an optional module is not loaded despite being available. For
+example the following command will prevent that C<YAML.pm> is being
+loaded:
-=head2 Maintaining the urllist parameter
+ cpan> o conf dontload_list push YAML
-If you have YAML.pm (or some other YAML module configured in
-C<yaml_module>) installed, CPAN.pm collects a few statistical data
-about recent downloads. You can view the statistics with the C<hosts>
-command or inspect them directly by looking into the C<FTPstats.yml>
-file in your C<cpan_home> directory.
+See the source for details.
-To get some interesting statistics it is recommended to set the
-C<randomize_urllist> parameter that introduces some amount of
-randomness into the URL selection.
+=item has_usable($module)
-=head2 prefs_dir for avoiding interactive questions (ALPHA)
+Returns true if the module is installed and is in a usable state. Only
+useful for a handful of modules that are used internally. See the
+source for details.
-(B<Note:> This feature has been introduced in CPAN.pm 1.8854 and is
-still considered experimental and may still be changed)
-
-The files in the directory specified in C<prefs_dir> are YAML files
-that specify how CPAN.pm shall treat distributions that deviate from
-the normal non-interactive model of building and installing CPAN
-modules.
-
-Some modules try to get some data from the user interactively thus
-disturbing the installation of large bundles like Phalanx100 or
-modules like Plagger.
-
-CPAN.pm can use YAML files to either pass additional arguments to one
-of the four commands, set environment variables or instantiate an
-Expect object that reads from the console and enters answers on your
-behalf (latter option requires Expect.pm installed). A further option
-is to apply patches from the local disk or from CPAN.
-
-CPAN.pm comes with a couple of such YAML files. The structure is
-currently not documented because in flux. Please see the distroprefs
-directory of the CPAN distribution for examples and follow the
-C<00.README> file in there.
-
-Please note that setting the environment variable PERL_MM_USE_DEFAULT
-to a true value can also get you a long way if you want to always pick
-the default answers. But this only works if the author of a package
-used the prompt function provided by ExtUtils::MakeMaker and if the
-defaults are OK for you.
+=item instance($module)
+
+The constructor for all the singletons used to represent modules,
+distributions, authors and bundles. If the object already exists, this
+method returns the object, otherwise it calls the constructor.
