+Why perl 5?
+-----------
+
+* Perl 5 is widely available on modern *nix systems with good a history
+ of backwards and forward compatibility.
+
+* git and SpamAssassin both use it, so it should be one less thing for
+ admins to install and waste disk space with.
+
+* Distributing compiled binaries has higher costs for storage/cache
+ space is required for each architecture. Having a runnable,
+ source-only distribution means any user already has access to all
+ of our source.
