+=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, waits for some regular
+expression and enters some answer. Needless to say that for the latter
+option Expect.pm needs to be installed.
+
+CPAN.pm comes with a couple of such YAML files. The structure is
+currently not documented. 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 apackage
+used the prompt function provided by ExtUtils::MakeMaker and if the
+defaults are OK for you.
