Note you can also type the following in Terminal to open Coco.app:
open -a Coco

For instance:
open -a Firefox
open -a Google\ Chrome
open -a TextEdit

You could also type:
open -a Maxima

I guess you are right in that the expectation is probably that someone
who downloads an app wants to use it as an app, and if they want to
use it in the command line or have scripts or other programs call them
they will arrange for it to work (eg by modifying the PATH or by
adding a symlink in a place that is already in the PATH).

You can learn more about "ln -s" by searching for it on the internet, eg
http://www.google.fr/search?q=%22ln+-s%22
