Subject: Re: appropriate use of constants

hi roob,

  if your program is also going to have some kind of settings manager,
so that the user can change various settings, you probably don't want
constants - but rather variables.  i'd put all of the settings into a
module, that you later include in your main file.  this way, if the
settings module is called `Settings`, and you have a variable in that
module called `@volume`, you can just call `Settings.volume` in the main
file to get the value.

  keep in mind that you'll also want to write in some way to create
default settings and a new settings file in case the original settings
file somehow goes missing...

  here's an example:
