 # this is the feisty meow host preparation script.  it installs all the packages required to run and build feisty meow scripts and applications.
 
-# hmmm: this script may still be a bit incomplete; we definitely use a lot of unix and linux tools in different scripts.

 # preconditions and dependencies--this script itself depends on:
 #   feisty meow
 #   bash
 #   anything else?
 
+# note that this list of items is never totally complete, since feisty meow keeps expanding and mutating.  for example, we now have a few
+# python scripts starting to sneak in.  there are assuredly lots of python packages we should be installing in here now, but we aren't yet.
+# this is a best effort script, to at least get feisty meow able to run its core scripts and to build.  although it's always appreciated
+# when things we rely on get installed too...
