It seems that the links are broken for your code examples. Are these still available? Thanks.
Unfortunately those files
are were no longer at the URLs pointed to because of the widely-known breakdown of the perlmonk.org server. Compounding that misfortune, yours truly has been "too busy" to go back and make sure that files from the old account are back in place.
I'll try to fix those links ASAP. Thank you very much for your interest in Makefile Reform :-).
Update: fixed URLs / file locations for the 2 pieces ("Before" and "After") [Sat Apr 26 10:43:42 UTC 2008]
