past the immediate impasse. Chainsaw, hand saw, or axe -- in the end,
all that matters is that the tree is felled. But this was but one of
many trees which I must fell, so other impasses are likely.
I am attempting to resurrect a project which I was forced to set aside
in mid-stream several years ago. That project necessitates recursion
to perform a series of simple, identical operations on several sets of
data, each of which involves a search-and-replace operation on
literally hundreds of files.
Because of the repetition, my approach back then was to create a set
of Perl scripts; I found it easier to utilize a sequence of about a
