Install name name ...

"Install Foo" means to make sure Foo has been loaded. If package Foo has already been installed, nothing more need be done. A package Foo is considered to be install if either: (1) there is a module named Foo, FooPackage, or FooImpl loaded, or (2) "Install Foo" has suceeded in the past. If not, Install looks for a load file for Foo and executes it. The load file is sought first in the current working directory, then in each directory in the command tool's search path. In each directory, files named either LoadFoo.cm or Foo.Load are considered load files. The most recently created load file in the first directory with any load files is taken. If no load file is found, Install fails.
