Subject: Re: New Ruby developer Rake questions

Thanks for the suggestion.  I'm having trouble making this work. I've 
created a couple test scripts to illustrate.  In the Raketest folder, I 
have the following  Rakefile.rb script:

task :default do
  sh "cd Child;rake"
end

The Child folder under this has the following Rakefile.rb:

task :default do
   puts "Child Rake Default task"
end

The following shows the result of running rake first in the child 
folder, then in the Raketest folder:

C:\Raketest\Child>rake
(in C:/Raketest/Child)
Child Rake Default task

C:\Raketest\Child>cd ..

C:\Raketest>rake
cd Child;rake
(in C:/Raketest)
The system cannot find the path specified.
rake aborted!
Command failed with status (1): [cd Child;rake...]
C:/Raketest/rakefile.rb:2
(See full trace by running task with --trace)

When I run rake in the child folder, it works.  When I run rake in the 
Raketest folder, I get the "The system cannot find the path specified." 
message.  So what am I missing?

Just for good measure, I uninstalled all versions of Rake (via gem) then 
installed the latest version, which didn't change anything.

I've attached my zipped contrived sample.  I'd appreciate any help.
