Execute a Rake task in another

It is easy to make one task dependent on another, for example:

task :one => [:two, :three]

executes task two, three, then one (I have to test that the order is really this). But how to execute task ":two" in the middle of the code of another task?

Here is the solution:

desc "This task executes task two in its code!"
task :one do

# ... do domething

ENV['PAR1'] = 'xxx'
ENV['PAR2'] = 'yyy'
Rake::Task[ "two" ].execute

# ... do something

end

the ENV assignments and execute call have a similar effect to executing in your shell:

rake two PAR1 = xxx, PAR2 = yyy

Yeah, Rake is a really easy and cool tool for every scripting need...
