Commit 093cc00cdd9d8cf31ecce5bc1dd3645c460a1b98 sets the AR environment variable
by default, but this causes the argyllcms Makefile to use the wrong command.
There are many more packages to fix, this is just a start.
Rules:
* Don't repeat the package name (not always that easy...)
* Start with capital letter
* Don't end with full stop
* Don't start with "The ..." or "A ..."
I've also added descriptions to some packages and rewritten others.
