You should definitely use version 5. Version 4 is old, limited, and
no longer maintained; its last patch (4.036) was in 1992, long ago and
far away. Sure, it's stable, but so is anything that's dead; in fact,
-perl4 had been called a dead, flea-bitten camel carcass. The most recent
-production release is 5.6 (although 5.005_03 is still supported).
-The most cutting-edge development release is 5.7. Further references
-to the Perl language in this document refer to the production release
-unless otherwise specified. There may be one or more official bug fixes
-by the time you read this, and also perhaps some experimental versions
-on the way to the next release. All releases prior to 5.004 were subject
-to buffer overruns, a grave security issue.

=head2 What are perl4 and perl5?
(Well, OK, maybe it's not quite that distinct, but you get the idea.)
If you want support and a reasonable guarantee that what you're
developing will continue to work in the future, then you have to run
-the supported version. As of January 2002 that probably means
-running either of the releases 5.6.1 (released in April 2001) or
-5.005_03 (released in March 1999), although 5.004_05 isn't that bad
-if you B<absolutely> need such an old version (released in April 1999)
-for stability reasons. Anything older than 5.004_05 shouldn't be used.

Of particular note is the massive bug hunt for buffer overflow
problems that went into the 5.004 release. All releases prior to
