=head1 STATUS
-This module will eventually be replaced by CPANPLUS. CPANPLUS is kind
-of a modern rewrite from ground up with greater extensibility and more
-features but no full compatibility. If you're new to CPAN.pm, you
-probably should investigate if CPANPLUS is the better choice for you.
-
-If you're already used to CPAN.pm you're welcome to continue using it.
-I intend to support it until somebody convinces me that there is a
-both superior and sufficiently compatible drop-in replacement.
+This module and its competitor, the CPANPLUS module, are both much
+cooler than the other.
=head1 COMPATIBILITY
All methods provided are accessible in a programmer style and in an
interactive shell style.
-=head2 Interactive Mode
+=head2 CPAN::shell([$prompt, $command]) Starting Interactive Mode
The interactive mode is entered by running
The first example will be driven by an object of the class
CPAN::Module, the second by an object of class CPAN::Distribution.
-=head2 Programmer's interface
+=head1 PROGRAMMER'S INTERFACE
If you do not enter the shell, the available shell commands are both
available as methods (C<CPAN::Shell-E<gt>install(...)>) and as
shell interface does that for you by including all currently installed
modules in a snapshot bundle file.
-=head2 Prerequisites
+=head1 PREREQUISITES
If you have a local mirror of CPAN and can access all files with
"file:" URLs, then you only need a perl better than perl5.003 to run
implemented for an external ftp command or for an external lynx
command.
+=head1 UTILITIES
+
=head2 Finding packages and VERSION
This module presumes that all packages on CPAN
of a personal CPAN. CPAN.pm on the non-networked machines works nicely
with this floppy. See also below the paragraph about CD-ROM support.
+=head2 Basic Utilities for Programmers
+
+=over 2
+
+=item has_inst($module)
+
+Returns true if the module is installed. See the source for details.
+
+=item has_usable($module)
+
+Returns true if the module is installed and several and is in a usable
+state. Only useful for a handful of modules that are used internally.
+See the source for details.
+
+=item instance($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.

=head1 CONFIGURATION
When the CPAN module is used for the first time, a configuration
build_cache size of cache for directories to build modules
build_dir locally accessible directory to build modules
+ bzip2 path to external prg
cache_metadata use serializer to cache metadata
commands_quote prefered character to use for quoting external
commands when running them. Defaults to double
quote on Windows, single tick everywhere else;
can be set to space to disable quoting
check_sigs if signatures should be verified
+ colorize_output boolean if Term::ANSIColor should colorize output
+ colorize_print Term::ANSIColor attributes for normal output
+ colorize_warn Term::ANSIColor attributes for warnings
+ commandnumber_in_prompt
+ boolean if you want to see current command number
cpan_home local directory reserved for this package
+ curl path to external prg
+ dontload_hash DEPRECATED
dontload_list arrayref: modules in the list will not be
loaded by the CPAN::has_inst() routine
+ ftp path to external prg
+ ftp_passive if set, the envariable FTP_PASSIVE is set for downloads
+ ftp_proxy proxy host for ftp requests
getcwd see below
+ gpg path to external prg
gzip location of external program gzip
histfile file to maintain history between sessions
histsize maximum number of lines to keep in histfile
+ http_proxy proxy host for http requests
inactivity_timeout breaks interactive Makefile.PLs or Build.PLs
after this many seconds inactivity. Set to 0 to
never break.
inhibit_startup_message
if true, does not print the startup message
keep_source_where directory in which to keep the source (if we do)
+ lynx path to external prg
make location of external make program
make_arg arguments that should always be passed to 'make'
make_install_make_command
command to use instead of './Build' when we are
in the install stage, for example 'sudo ./Build'
mbuildpl_arg arguments passed to 'perl Build.PL'
+ ncftp path to external prg
+ ncftpget path to external prg
+ no_proxy don't proxy to these hosts/domains (comma separated list)
pager location of external program more (or any pager)
+ password your password if you CPAN server wants one
prefer_installer legal values are MB and EUMM: if a module comes
with both a Makefile.PL and a Build.PL, use the
former (EUMM) or the latter (MB); if the module
proxy_user username for accessing an authenticating proxy
proxy_pass password for accessing an authenticating proxy
scan_cache controls scanning of cache ('atstart' or 'never')
+ shell your favorite shell
+ show_upload_date boolean if commands should try to determine upload date
tar location of external program tar
term_is_latin if true internal UTF-8 is translated to ISO-8859-1
(and nonsense for characters outside latin range)
+ term_ornaments boolean to turn ReadLine ornamenting on/off
test_report email test reports (if CPAN::Reporter is installed)
unzip location of external program unzip
urllist arrayref to nearby CPAN sites (or equivalent locations)
+ username your username if you CPAN server wants one
wait_list arrayref to a wait server to try (See CPAN::WAIT)
- ftp_passive if set, the envariable FTP_PASSIVE is set for downloads
- ftp_proxy, } the three usual variables for configuring
- http_proxy, } proxy requests. Both as CPAN::Config variables
- no_proxy } and as environment variables configurable.
+ wget path to external prg
You can set and query each of these options interactively in the cpan
shell with the command set defined within the C<o conf> command:

-=head2 Note on config variable getcwd
+=head2 CPAN::anycwd($path): Note on config variable getcwd
CPAN.pm changes the current working directory often and needs to
determine its own current working directory. Per default it uses
Cwd::cwd but if this doesn't work on your system for some reason,
alternatives can be configured according to the following table:
- cwd Cwd::cwd
- getcwd Cwd::getcwd
- fastcwd Cwd::fastcwd
- backtickcwd external command cwd
