-
-# One use of the queue is to determine if we should or shouldn't
-# announce the availability of a new CPAN module
-
-# Now we try to use it for dependency tracking. For that to happen
-# we need to draw a dependency tree and do the leaves first. This can
-# easily be reached by running CPAN.pm recursively, but we don't want
-# to waste memory and run into deep recursion. So what we can do is
-# this:
-
-# CPAN::Queue is the package where the queue is maintained. Dependencies
-# often have high priority and must be brought to the head of the queue,
-# possibly by jumping the queue if they are already there. My first code
-# attempt tried to be extremely correct. Whenever a module needed
-# immediate treatment, I either unshifted it to the front of the queue,
-# or, if it was already in the queue, I spliced and let it bypass the
-# others. This became a too correct model that made it impossible to put
-# an item more than once into the queue. Why would you need that? Well,
-# you need temporary duplicates as the manager of the queue is a loop
-# that
-#
-# (1) looks at the first item in the queue without shifting it off
-#
-# (2) cares for the item
-#
-# (3) removes the item from the queue, *even if its agenda failed and
-# even if the item isn't the first in the queue anymore* (that way
-# protecting against never ending queues)
-#
-# So if an item has prerequisites, the installation fails now, but we
-# want to retry later. That's easy if we have it twice in the queue.
-#
-# I also expect insane dependency situations where an item gets more
-# than two lives in the queue. Simplest example is triggered by 'install
-# Foo Foo Foo'. People make this kind of mistakes and I don't want to
-# get in the way. I wanted the queue manager to be a dumb servant, not
-# one that knows everything.
-#
-# Who would I tell in this model that the user wants to be asked before
-# processing? I can't attach that information to the module object,
-# because not modules are installed but distributions. So I'd have to

+
+=head1 COMPATIBILITY
+
+CPAN.pm is regularly tested to run under 5.004, 5.005, and assorted
+newer versions. It is getting more and more difficult to get the
+minimal prerequisites working on older perls. It is close to
+impossible to get the whole Bundle::CPAN working there. If you're in
+the position to have only these old versions, be advised that CPAN is
+designed to work fine without the Bundle::CPAN installed.
+
+To get things going, note that GBARR/Scalar-List-Utils-1.18.tar.gz is
+compatible with ancient perls and that File::Temp is listed as a
+prerequisite but CPAN has reasonable workarounds if it is missing.
=head1 DESCRIPTION
The CPAN module is designed to automate 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 raw data from the net.
Modules 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
-'bundles' of modules. Bundles simplify the handling of sets of
-related modules. See BUNDLES below.
+I<bundles> of modules. Bundles simplify the handling of sets of

The package contains a session manager and a cache manager. There is
no status retained between sessions. The session manager keeps track
the make processes and deletes excess space according to a simple FIFO
mechanism.
-For extended searching capabilities there's a plugin for CPAN available,
-L<CPAN::WAIT>. C<CPAN::WAIT> is a full-text search engine that indexes
-all documents available in CPAN authors directories. If C<CPAN::WAIT>
-is installed on your system, the interactive shell of <CPAN.pm> will
-enable the C<wq>, C<wr>, C<wd>, C<wl>, and C<wh> commands which send
-queries to the WAIT server that has been configured for your

The interactive mode is entered by running
Once you are on the command line, type 'h' and the rest should be
self-explanatory.
+The function call C<shell> takes two optional arguments, one is the
+prompt, the second is the default initial command line (the latter
+only works if a real ReadLine interface module is installed).

The most common uses of the interactive modes are

The principle is that the number of found objects influences how an
-item is displayed. If the search finds one item, the result is displayed
-as object-E<gt>as_string, but if we find more than one, we display
-each as object-E<gt>as_glimpse. E.g.
-
- cpan> a ANDK
- Author id = ANDK
- EMAIL a.koenig@franz.ww.TU-Berlin.DE
- FULLNAME Andreas König

- cpan> a /andk/

- EMAIL a.koenig@franz.ww.TU-Berlin.DE

+item is displayed. If the search finds one item, the result is
+displayed with the rather verbose method C<as_string>, but if we find
+more than one, we display each object with the terse method
+C<as_glimpse>.
=item make, test, install, clean modules or distributions
-These commands take any number of arguments and investigates what is
+These commands take any number of arguments and investigate what is
necessary to perform the action. If the argument is a distribution
file name (recognized by embedded slashes), it is processed. If it is
a module, CPAN determines the distribution file in which this module
is included and processes that, following any dependencies named in
-the module's Makefile.PL (this behavior is controlled by
-
I<prerequisites_policy>.)
+the module's META.yml or Makefile.PL (this behavior is controlled by
+
the configuration parameter C<prerequisites_policy>.)
Any C<make> or C<test> are run unconditionally. An
CPAN checks if an install is actually needed for it and prints
I<module up to date> in the case that the distribution file containing
-the module doesnE<39>t need to be updated.
+the module doesn't need to be updated.
CPAN also keeps track of what it has done within the current session
-and doesnE<39>t try to build a package a second time regardless if it
-succeeded or not. The C<force> command takes as a first argument the
-method to invoke (currently: C<make>, C<test>, or C<install>) and executes the
-command from scratch.
+and doesn't try to build a package a second time regardless if it
+succeeded or not. The C<force> pragma may precede another command
+(currently: C<make>, C<test>, or C<install>) and executes the
+command from scratch and tries to continue in case of some errors.
Example:
OpenGL-0.4/COPYRIGHT
[...]
+The C<notest> pragma may be set to skip the test part in the build
+process.
+
+Example:
+
+ cpan> notest install Tk
+
A C<clean> command results in a
make clean
being executed within the distribution file's working directory.
-=item readme, look module or distribution
+=item get, readme, perldoc, look module or distribution
-These two commands take only one argument, be it a module or a
-distribution file. C<readme> unconditionally runs, displaying the
-README of the associated distribution file. C<Look> gets and
-untars (if not yet done) the distribution file, changes to the
+C<get> downloads a distribution file without further action. C<readme>
+displays the README file of the associated distribution. C<Look> gets
+and untars (if not yet done) the distribution file, changes to the
appropriate directory and opens a subshell process in that directory.
+C<perldoc> displays the pod documentation of the module in html or
+plain text format.
+
+=item ls author
+
+=item ls globbing_expression
+
+The first form lists all distribution files in and below an author's
+CPAN directory as they are stored in the CHECKUMS files distributed on
+CPAN. The listing goes recursive into all subdirectories.
+
+The second form allows to limit or expand the output with shell
+globbing as in the following examples:
+
+ ls JV/make*
+ ls GSAR/*make*
+ ls */*make*
+
+The last example is very slow and outputs extra progress indicators
+that break the alignment of the result.
+
+Note that globbing only lists directories explicitly asked for, for
+example FOO/* will not list FOO/bar/Acme-Sthg-n.nn.tar.gz. This may be
+regarded as a bug and may be changed in future versions.
+
+=item failed
+
+The C<failed> command reports all distributions that failed on one of
+C<make>, C<test> or C<install> for some reason in the currently
+running shell session.
+
+=item Lockfile
+
+Interactive sessions maintain a lockfile, per default C<~/.cpan/.lock>
+(but the directory can be configured via the C<cpan_home> config
+variable). The shell is a bit picky if you try to start another CPAN
+session. It dies immediately if there is a lockfile and the lock seems
+to belong to a running process. In case you want to run a second shell
+session, it is probably safest to maintain another directory, say
+C<~/.cpan-for-X/> and a C<~/.cpan-for-X/CPAN/MyConfig.pm> that
+contains the configuration options. Then you can start the second
+shell with
+
+ perl -I ~/.cpan-for-X -MCPAN::MyConfig -MCPAN -e shell
=item Signals

installed within @INC. The name of the bundle file is based on the
current date and a counter.
+=head2 hosts
+
+This commands provides a statistical overview over recent download
+activities. The data for this is collected in the YAML file
+C<FTPstats.yml> in your C<cpan_home> directory. If no YAML module is
+configured or YAML not installed, then no stats are provided.
+
+=head2 mkmyconfig
+
+mkmyconfig() writes your own CPAN::MyConfig file into your ~/.cpan/
+directory so that you can save your own preferences instead of the
+system wide ones.
+
=head2 recompile
recompile() is a very special command in that it takes no argument and
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.
+invoke CPAN's recompile on the second architecture and you'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 report Bundle|Distribution|Module
+
+The C<report> command temporarily turns on the C<test_report> config
+variable, then runs the C<force test> command with the given
+arguments. The C<force> pragma is used to re-run the tests and repeat
+every step that might have failed before.
+
+=head2 upgrade [Module|/Regex/]...
+
+The C<upgrade> command first runs an C<r> command with the given
+arguments and then installs the newest versions of all modules that
+were listed by that.
+
=head2 The four C<CPAN::*> Classes: Author, Bundle, Module, Distribution
Although it may be considered internal, the class hierarchy does matter
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
+module version number which will also be reflected in the distribution
+name when you run 'make dist'), so the really hottest and newest
+distribution 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
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
+=head2 Integrating local directories
+
+Distribution objects are normally distributions from the CPAN, but
+there is a slightly degenerate case for Distribution objects, too,
+normally only needed by developers. If a distribution object ends with
+a dot or is a dot by itself, then it represents a local directory and
+all actions such as C<make>, C<test>, and C<install> are applied
+directly to that directory. This gives the command C<cpan .> an
+interesting touch: while the normal mantra of installing a CPAN module
+without CPAN.pm is one of
+
+ perl Makefile.PL perl Build.PL
+ ( go and get prerequisites )
+ make ./Build
+ make test ./Build test
+ make install ./Build install
+
+the command C<cpan .> does all of this at once. It figures out which
+of the two mantras is appropriate, fetches and installs all
+prerequisites, cares for them recursively and finally finishes the
+installation of the module in the current directory, be it a CPAN
+module or not.
+
+=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;

+Returns a list of objects' IDs contained in a bundle. The associated
+objects may be bundles, modules or distributions.
+
+=item CPAN::Bundle::force($method,@args)
+
+Forces CPAN to perform a task that normally would have failed. Force
+takes as arguments a method name to be called and any number of
+additional arguments that should be passed to the called method. The
+internals of the object get the needed changes so that CPAN.pm does
+not refuse to take the action. The C<force> is passed recursively to
+all contained objects.
+
+=item CPAN::Bundle::get()
+
+Recursively runs the C<get> method on all items contained in the bundle
+
+=item CPAN::Bundle::inst_file()
+
+Returns the highest installed version of the bundle in either @INC or
+C<$CPAN::Config->{cpan_home}>. Note that this is different from
+CPAN::Module::inst_file.
+
+=item CPAN::Bundle::inst_version()
+
+Like CPAN::Bundle::inst_file, but returns the $VERSION
+
+=item CPAN::Bundle::uptodate()

+
+Changes to the directory where the distribution has been unpacked and
+runs C<make clean> there.
+
+=item CPAN::Distribution::containsmods()
+
+Returns a list of IDs of modules contained in a distribution file.
+Only works for distributions listed in the 02packages.details.txt.gz
+file. This typically means that only the most recent version of a
+distribution is covered.
+
+=item CPAN::Distribution::cvs_import()
+
+Changes to the directory where the distribution has been unpacked and
+runs something like
+
+ cvs -d $cvs_root import -m $cvs_log $cvs_dir $userid v$version
+
+there.

+=item CPAN::Distribution::dir()
+
+Returns the directory into which this distribution has been unpacked.
+
+=item CPAN::Distribution::force($method,@args)
+
+Forces CPAN to perform a task that normally would have failed. 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.
+
+=item CPAN::Distribution::get()
+
+Downloads the distribution from CPAN and unpacks it. Does nothing if
+the distribution has already been downloaded and unpacked within the
+current session.
+
+=item CPAN::Distribution::install()
+
+Changes to the directory where the distribution has been unpacked and
+runs the external command C<make install> there. If C<make> has not
+yet been run, it will be run first. A C<make test> will be issued in
+any case and if this fails, the install will be canceled. The
+cancellation can be avoided by letting C<force> run the C<install> for
+you.
+
+This install method has only the power to install the distribution if
+there are no dependencies in the way. To install an object and all of
+its dependencies, use CPAN::Shell->install.

+=item CPAN::Distribution::isa_perl()
+
+Returns 1 if this distribution file seems to be a perl distribution.

+=item CPAN::Distribution::make()
+
+First runs the C<get> method to make sure the distribution is
+downloaded and unpacked. Changes to the directory where the
+distribution has been unpacked and runs the external commands C<perl
+Makefile.PL> or C<perl Build.PL> and C<make> there.
+
+=item CPAN::Distribution::perldoc()
+
+Downloads the pod documentation of the file associated with a
+distribution (in html format) and runs it through the external
+command lynx specified in C<$CPAN::Config->{lynx}>. If lynx
+isn't available, it converts it to plain text with external
+command html2text and runs it through the pager specified
+in C<$CPAN::Config->{pager}>
+
+=item CPAN::Distribution::prefs()
+
+Returns the hash reference from the first matching YAML file that the
+user has deposited in the C<prefs_dir/> directory. The first
+succeeding match wins. The files in the C<prefs_dir/> are processed
+alphabetically and the canonical distroname (e.g.
+AUTHOR/Foo-Bar-3.14.tar.gz) is matched against the regular expressions
+stored in the $root->{match}{distribution} attribute value.
+Additionally all module names contained in a distribution are matched
+agains the regular expressions in the $root->{match}{module} attribute
+value. The two match values are ANDed together. Each of the two
+attributes are optional.
+
+=item CPAN::Distribution::prereq_pm()
+
+Returns the hash reference that has been announced by a distribution
+as the merge of the C<requires> element and the C<build_requires>
+element of the META.yml or the C<PREREQ_PM> hash in the
+C<Makefile.PL>. Note: works only after an attempt has been made to
+C<make> the distribution. Returns undef otherwise.

+
+Changes to the directory where the distribution has been unpacked and
+runs C<make test> there.
+
+=item CPAN::Distribution::uptodate()
+
+Returns 1 if all the modules contained in the distribution are
+uptodate. Relies on containsmods.

+
+Reloads all indices if they have not been read for more than
+C<$CPAN::Config->{index_expire}> days.
+
+=item CPAN::InfoObj::dump()
+
+CPAN::Author, CPAN::Bundle, CPAN::Module, and CPAN::Distribution
+inherit this method. It prints the data structure associated with an
+object. Useful for debugging. Note: the data structure is considered
+internal and thus subject to change without notice.
+
+=item CPAN::Module::as_glimpse()
+
+Returns a one-line description of the module in four columns: The
+first column contains the word C<Module>, the second column consists
+of one character: an equals sign if this module is already installed

+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.
-In interactive mode you can try "o debug" which will list options for
-debugging the various parts of the package. The output may not be very
-useful for you as it's just a by-product of my own testing, but if you
-have an idea which part of the package may have a bug, it's sometimes
-worth to give it a try and send me more specific output. You should
-know that "o debug" has built-in completion support.
+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

+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

+
=head1 CONFIGURATION
-When the CPAN module is installed, a site wide configuration file is
-created as CPAN/Config.pm. The default values defined there can be
-overridden in another configuration file: CPAN/MyConfig.pm. You can
-store this file in $HOME/.cpan/CPAN/MyConfig.pm if you want, because
-$HOME/.cpan is added to the search path of the CPAN module before the
-use() or require() statements.
+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.
+

+=head2 CPAN::anycwd($path): Note on config variable getcwd
+
+CPAN.pm changes the current working directory often and needs to

+Cwd::cwd but if this doesn't work on your system for some reason,
+alternatives can be configured according to the following table:

urllist parameters are URLs according to RFC 1738. We do a little

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 prefs_dir for avoiding interactive questions (ALPHA)
+
+(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 README
+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.

=head1 SECURITY
There's no strong security layer in CPAN.pm. CPAN.pm helps you to
install foreign, unmasked, unsigned code on your machine. We compare
to a checksum that comes from the net just as the distribution file

+itself. But we try to make it easy to add security on demand:
+
+=head2 Cryptographically signed modules
+
+Since release 1.77 CPAN.pm has been able to verify cryptographically
+signed module distributions using Module::Signature. The CPAN modules
+can be signed by their authors, thus giving more security. The simple
+unsigned MD5 checksums that were used before by CPAN protect mainly
+against accidental file corruption.
+
+You will need to have Module::Signature installed, which in turn
+requires that you have at least one of Crypt::OpenPGP module or the
+command-line F<gpg> tool installed.
+
+You will also need to be able to connect over the Internet to the public
+keyservers, like pgp.mit.edu, and their port 11731 (the HKP protocol).
+
+The configuration parameter check_sigs is there to turn signature
+checking on or off.
=head1 EXPORT

for this is that the primary use is intended for the cpan shell or for

+
+=head1 ENVIRONMENT
+
+When the CPAN shell enters a subshell via the look command, it sets
+the environment CPAN_SHELL_LEVEL to 1 or increments it if it is
+already set.
+
+When the config variable ftp_passive is set, all downloads will be run
+with the environment variable FTP_PASSIVE set to this value. This is
+in general a good idea as it influences both Net::FTP and LWP based
+connections. The same effect can be achieved by starting the cpan

Firewalls can be categorized into three basic types.

+=head2 Configuring lynx or ncftp for going through a firewall
+
+If you can go through your firewall with e.g. lynx, presumably with a
+command such as
+
+ /usr/local/bin/lynx -pscott:tiger
+
+then you would configure CPAN.pm with the command
+
+ o conf lynx "/usr/local/bin/lynx -pscott:tiger"
+
+That's all. Similarly for ncftp or ftp, you would configure something
+like
+
+ o conf ncftp "/usr/bin/ncftp -f /home/scott/ncftplogin.cfg"
+
+Your mileage may vary...
+
+=head1 FAQ
+
+=over 4
+
+=item 1)
+
+I installed a new version of module X but CPAN keeps saying,
+I have the old version installed
+
+Most probably you B<do> have the old version installed. This can
+happen if a module installs itself into a different directory in the
+@INC path than it was previously installed. This is not really a
+CPAN.pm problem, you would have the same problem when installing the
+module manually. The easiest way to prevent this behaviour is to add
+the argument C<UNINST=1> to the C<make install> call, and that is why
+many people add this argument permanently by configuring
+
+ o conf make_install_arg UNINST=1
+
+=item 2)
+
+So why is UNINST=1 not the default?
+
+Because there are people who have their precise expectations about who
+may install where in the @INC path and who uses which @INC array. In
+fine tuned environments C<UNINST=1> can cause damage.
+
+=item 3)
+
+I want to clean up my mess, and install a new perl along with
+all modules I have. How do I go about it?
+
+Run the autobundle command for your old perl and optionally rename the
+resulting bundle file (e.g. Bundle/mybundle.pm), install the new perl
+with the Configure option prefix, e.g.
+
+ ./Configure -Dprefix=/usr/local/perl-5.6.78.9
+
+Install the bundle file you produced in the first step with something like
+
+ cpan> install Bundle::mybundle
+
+and you're done.
+
+=item 4)
+
+When I install bundles or multiple modules with one command
+there is too much output to keep track of.
+
+You may want to configure something like
+
+ o conf make_arg "| tee -ai /root/.cpan/logs/make.out"
+ o conf make_install_arg "| tee -ai /root/.cpan/logs/make_install.out"
+
+so that STDOUT is captured in a file for later inspection.
+
+
+=item 5)
+
+I am not root, how can I install a module in a personal directory?
+
+First of all, you will want to use your own configuration, not the one
+that your root user installed. If you do not have permission to write
+in the cpan directory that root has configured, you will be asked if
+you want to create your own config. Answering "yes" will bring you into
+CPAN's configuration stage, using the system config for all defaults except
+things that have to do with CPAN's work directory, saving your choices to
+your MyConfig.pm file.
+
+You can also manually initiate this process with the following command:
+
+ % perl -MCPAN -e 'mkmyconfig'
+
+or by running
+
+ mkmyconfig
+
+from the CPAN shell.
+
+You will most probably also want to configure something like this:
+
+ o conf makepl_arg "LIB=~/myperl/lib \
+ INSTALLMAN1DIR=~/myperl/man/man1 \
+ INSTALLMAN3DIR=~/myperl/man/man3"
+
+You can make this setting permanent like all C<o conf> settings with
+C<o conf commit>.
+
+You will have to add ~/myperl/man to the MANPATH environment variable
+and also tell your perl programs to look into ~/myperl/lib, e.g. by
+including
+
+ use lib "$ENV{HOME}/myperl/lib";
+
+or setting the PERL5LIB environment variable.
+
+While we're speaking about $ENV{HOME}, it might be worth mentioning,
+that for Windows we use the File::HomeDir module that provides an
+equivalent to the concept of the home directory on Unix.
+
+Another thing you should bear in mind is that the UNINST parameter can
+be dnagerous when you are installing into a private area because you
+might accidentally remove modules that other people depend on that are
+not using the private area.
+
+=item 6)
+
+How to get a package, unwrap it, and make a change before building it?
+
+Have a look at the C<look> (!) command.
+
+=item 7)
+
+I installed a Bundle and had a couple of fails. When I
+retried, everything resolved nicely. Can this be fixed to work
+on first try?
+
+The reason for this is that CPAN does not know the dependencies of all
+modules when it starts out. To decide about the additional items to
+install, it just uses data found in the META.yml file or the generated
+Makefile. An undetected missing piece breaks the process. But it may
+well be that your Bundle installs some prerequisite later than some
+depending item and thus your second try is able to resolve everything.
+Please note, CPAN.pm does not know the dependency tree in advance and
+cannot sort the queue of things to install in a topologically correct
+order. It resolves perfectly well IF all modules declare the
+prerequisites correctly with the PREREQ_PM attribute to MakeMaker or
+the C<requires> stanza of Module::Build. For bundles which fail and
+you need to install often, it is recommended to sort the Bundle
+definition file manually.
+
+=item 8)
+
+In our intranet we have many modules for internal use. How
+can I integrate these modules with CPAN.pm but without uploading
+the modules to CPAN?
+
+Have a look at the CPAN::Site module.
+
+=item 9)
+
+When I run CPAN's shell, I get an error message about things in my
+/etc/inputrc (or ~/.inputrc) file.
+
+These are readline issues and can only be fixed by studying readline
+configuration on your architecture and adjusting the referenced file
+accordingly. Please make a backup of the /etc/inputrc or ~/.inputrc
+and edit them. Quite often harmless changes like uppercasing or
+lowercasing some arguments solves the problem.
+
+=item 10)
+
+Some authors have strange characters in their names.
+
+Internally CPAN.pm uses the UTF-8 charset. If your terminal is
+expecting ISO-8859-1 charset, a converter can be activated by setting
+term_is_latin to a true value in your config file. One way of doing so
+would be
+
+ cpan> o conf term_is_latin 1
+
+If other charset support is needed, please file a bugreport against
+CPAN.pm at rt.cpan.org and describe your needs. Maybe we can extend
+the support or maybe UTF-8 terminals become widely available.
+
+=item 11)
+
+When an install fails for some reason and then I correct the error
+condition and retry, CPAN.pm refuses to install the module, saying
+C<Already tried without success>.
+
+Use the force pragma like so
+
+ force install Foo::Bar
+
+This does a bit more than really needed because it untars the
+distribution again and runs make and test and only then install.
+
+Or, if you find this is too fast and you would prefer to do smaller
+steps, say
+
+ force get Foo::Bar
+
+first and then continue as always. C<Force get> I<forgets> previous
+error conditions.
+
+Or you can use
+
+ look Foo::Bar
+
+and then 'make install' directly in the subshell.
+
+Or you leave the CPAN shell and start it again.
+
+For the really curious, by accessing internals directly, you I<could>
+
+ !delete CPAN::Shell->expandany("Foo::Bar")->distribution->{install}
+
+but this is neither guaranteed to work in the future nor is it a
+decent command.
+
+=item 12)
+
+How do I install a "DEVELOPER RELEASE" of a module?
+
+By default, CPAN will install the latest non-developer release of a
+module. If you want to install a dev release, you have to specify the
+partial path starting with the author id to the tarball you wish to
+install, like so:
+
+ cpan> install KWILLIAMS/Module-Build-0.27_07.tar.gz
+
+Note that you can use the C<ls> command to get this path listed.
+
+=item 13)
+
+How do I install a module and all its dependencies from the commandline,
+without being prompted for anything, despite my CPAN configuration
+(or lack thereof)?
+
+CPAN uses ExtUtils::MakeMaker's prompt() function to ask its questions, so
+if you set the PERL_MM_USE_DEFAULT environment variable, you shouldn't be
+asked any questions at all (assuming the modules you are installing are
+nice about obeying that variable as well):
+
+ % PERL_MM_USE_DEFAULT=1 perl -MCPAN -e 'install My::Module'
+
+=item 14)
+
+How do I create a Module::Build based Build.PL derived from an
+ExtUtils::MakeMaker focused Makefile.PL?

+
+=item 15)
+
+What's the best CPAN site for me?
+
+The urllist config parameter is yours. You can add and remove sites at
+will. You should find out which sites have the best uptodateness,
+bandwidth, reliability, etc. and are topologically close to you. Some
+people prefer fast downloads, others uptodateness, others reliability.
+You decide which to try in which order.
