If you can do these things, you've started on the long road to Perl porting.
Thanks for wanting to help make Perl better - and happy hacking!
+=head2 Metaphoric Quotations
+
+If you recognized the quote about the Road above, you're in luck.
+
+Most software projects begin each file with a literal description of each
+file's purpose. Perl instead begins each with a literary allusion to that
+file's purpose.
+
+Like chapters in many books, all top-level Perl source files (along with a
+few others here and there) begin with an epigramic inscription that alludes,
+indirectly and metaphorically, to the material you're about to read.
+
+Quotations are taken from writings of J.R.R Tolkien pertaining to his
+Legendarium, almost always from I<The Lord of the Rings>. Chapters and
+page numbers are given using the following editions:
+
+=over 4
+
+=item *
+
+I<The Hobbit>, by J.R.R. Tolkien. The hardcover, 70th-anniversary
+edition of 2007 was used, published in the UK by Harper Collins Publishers
+and in the US by the Houghton Mifflin Company.
+
+=item *
+
+I<The Lord of the Rings>, by J.R.R. Tolkien. The hardcover,
+50th-anniversary edition of 2004 was used, published in the UK by Harper
+Collins Publishers and in the US by the Houghton Mifflin Company.
+
+=item *
+
+I<The Lays of Beleriand>, by J.R.R. Tolkien and published posthumously by his
+son and literary executor, C.J.R. Tolkien, being the 3rd of the 12 volumes
+in Christopher's mammoth I<History of Middle Earth>. Page numbers derive
+from the hardcover edition, first published in 1983 by George Allen &
+Unwin; no page numbers changed for the special 3-volume omnibus edition of
+2002 or the various trade-paper editions, all again now by Harper Collins
+or Houghton Mifflin.
+
+=back
+
+Other JRRT books fair game for quotes would thus include I<The Adventures of
+Tom Bombadil>, I<The Silmarillion>, I<Unfinished Tales>, and I<The Tale of
+the Children of Hurin>, all but the first posthumously assembled by CJRT.
+But I<The Lord of the Rings> itself is perfectly fine and probably best to
+quote from, provided you can find a suitable quote there.
+
+So if you were to supply a new, complete, top-level source file to add to
+Perl, you should conform to this peculiar practice by yourself selecting an
+appropriate quotation from Tolkien, retaining the original spelling and
+punctuation and using the same format the rest of the quotes are in.
+Indirect and oblique is just fine; remember, it's a metaphor, so being meta
+is, after all, what it's for.
