 # CaRMtl
 
-This is a copy of CaRMetal 4.2.8 (see http://carmetal.org) for tweaking and hacking on it, not a fork or attempt to take it over! See README.
+This repository is a copy of CaRMetal 4.2.8 (see http://carmetal.org) for
+tweaking and hacking on it. I created it because there did not seem to be a
+public code repository for CaRMetal, but there were a number of small projects
+I wanted to try on its codebase. My intention is to offer all of the changes
+pursued here back to the maintainers of CaRMetal, if they are receptive. Thus,
+this repository is not a fork or attempt to take over CaRMetal.
+
+As such, I wasn't sure what name to give the repository; using exactly
+CaRMetal seemed presumptuous, but making it too different seemed too much like
+this was intended as an independent project. Hence, CaRMtl. (Also, it's an
+awful enough name to be clear that this couldn't be an independent project
+because if it were, I would surely pick a better name, like CaRWaX or
+something ;-)
+
+Happy geometring, Glen.
