Hmmm.... reversible...
Do you mean like combining these options to the "install" program with
something in your build system that'll rename the (most recent) backup
copies to their original names and thus effectively undo the most recent
build?
-b Backup any existing files before overwriting them by renaming
them to file.old. See -B for specifying a different backup suf-
fix.
-B suffix
Use suffix as the backup suffix if -b is given. If suffix con-
tains a '%' sign, a numbered backup will be performed, and the
%-pattern will be expanded using sprintf(3), given an integer
counter as the backup number. The counter used starts from 0,
and the first available name resulting from the expansion is
used.

I think that's "backwards", if I might say so....
You want to be changing the checked out copy and then installing it into
the "production" location, perhaps after first testing it, and of course
performing any necessary transformations (such as compiling, or
replacing place-holder-tags with site-specific strings, etc.) on the way
through....

Ah, but that's where a makefile or some other build and/or install
script makes thing so easy! It "remembers" everything for you *and* it
takes care of all the messy details and boring redundant steps. You
just have to invoke it when you're ready and then sit back and relax
while all the magic happens....
