appropriate directory and opens a subshell process in that directory.

This enables the programmer to do operations that combine

}
perl -e 'use CPAN; CPAN::Shell->r;'
-If you don't want to get any output if all modules are up to date, you

+
+=item CPAN::Bundle::inst_file()

+
+Returns a list of IDs of modules contained in a distribution file.
+Only works for distributions listed in the 02packages.details.txt.gz

+cancellation can be avoided by letting C<force> run the C<install> for
+you.
+
+=item CPAN::Distribution::isa_perl()

+=item CPAN::InfoObj::dump()
+
+CPAN::Author, CPAN::Bundle, CPAN::Module, and CPAN::Distribution

+object. Useful for debugging. Note: the data structure is considered
+internal and thus subject to change without notice.

+Forces CPAN to perform a task that normally would have failed. Force

+
+Runs a get on the distribution associated with this module.

+
+Returns the version number of the module in readable format.
+
+=item CPAN::Module::install()
+
+Runs an C<install> on the distribution associated with this module.

-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 configuration dialog can be started any time later again by
+issueing the command C< o conf init > in the CPAN shell.
Currently the following keys in the hash reference $CPAN::Config are
defined:

+When I run CPAN's shell, I get error msg about line 1 to 4,
+setting meta input/output via the /etc/inputrc file.
+
+Some versions of readline are picky about capitalization in the
+/etc/inputrc file and specifically RedHat 6.2 comes with a
+/etc/inputrc that contains the word C<on> in lowercase. Change the
+occurrences of C<on> to C<On> and the bug should disappear.

+
+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> ! $CPAN::Config->{term_is_latin}=1
+
+Extended support for converters will be made available as soon as perl
+becomes stable with regard to charset issues.

We should give coverage for B<all> of the CPAN and not just the PAUSE

PAUSE plus the clpa/, doc/, misc/, ports/, and src/.
Future development should be directed towards a better integration of
