rake variables

I'm a rake beginner with a couple of questions:

(1) Is there any way to set rake options from the within the Rakefile,
as though they had been specified on the command-line? I always want to
run a particular Rakefile with particular options (e.g. -s).

(2) It seems rake either gives way too much info, or not enough. I want
Make-like behavior: Don't bother telling me about stuff you didn't have
to build, but do tell me when you're actually building something.

I see the potential, and I like it, but I'm starting to feel like I need
a separate Makefile just to run rake.

Can anyone recommend a more appropriate forum for these questions?

The short answer to this is no. The long answer is that you can use
rake as a library, and within your "rake replacement" script,
preconfigure Rake.application.options however you so choose.

I've just patched rake with support for a RAKEOPT environment variable:

http://github.com/jeffs/rake/t...

$ echo 'task :default do |t| puts t.name end' > Rakefile
$ rake
(in /Users/jeff)
default
$ RAKEOPT=-s rake
default
$

Merged into Jim Weirich's mainline:

Thank you, Jim.
