+CPAN is the world-wide archive of perl resources. It consists of about
+100 sites that all replicate the same contents all around the globe.
+Many countries have at least one CPAN site already. The resources
+found on CPAN are easily accessible with the CPAN.pm module. If you
+want to use CPAN.pm, you have to configure it properly.
+
+If you do not want to enter a dialog now, you can answer 'no' to this

+dialog anytime later by typing 'o conf init' at the cpan prompt.)

+
+The following questions are intended to help you with the

+
+If you like, I can cache the source files after I build them. Doing
+so means that, if you ever rebuild that module in the future, the
+files will be taken from the cache. The tradeoff is that it takes up
+space. How much space would you like to allocate to this cache? (If
+you don\'t want me to keep a cache, answer 0.)

+range. If your terminal supports UTF-8, you should say no to the next
+question. If it supports ISO-8859-1 (also known as LATIN1) then you
+should say yes. If it supports neither, your answer does not matter
