Thorsten: I might consider using the dispatcher in the future, if I need to make more changes to the pelt skin. For now, I will settle with hacking pelt to fit my needs. :)
David: I copied the "common" skin because the documentation I read about creating a new skin said to do so. I should have been more clear about which changes I wanted to get committed. I wanted my changes to the pelt skin to be committed, not my entire copied skin. If you use "grep -F" to match a fixed string then you do not need to escape the period character in the pattern as you do when using grep to match a regex. I am not sure how portable "grep -F" is, though. It works with GNU grep, which is pretty much all that matters in the desktop Linux world. :) Brian: Thank you so much! :D pelt-brolin is successfully using the "rev_id" metadata property from my source file now! David: You are correct. I realise that the behaviour of my variable is confusing. My plan was to get things working first, then worry about making the configuration more logical. I know there are plenty of existing examples. I also know how to use find(1). The problem was that I could not find any examples of what I was trying to do: extract text from a "meta" element in the "header" section of a source file. I did search for a suitable example, but could not find one. That is why I decided to ask on this list.
