Heh ... sorry. I need to write some docs. But I didn't want to
delay the new version for the write-up.

Close. You have to obey the rules that the shell imposes. So, either:
rake upload[filename1,filename2]
or
rake "upload[filename1, filename2]"
(the first has no spaces, the second quotes the arguments. Rules
vary on windows and non-ksh/bash shells).

You have to tell the task the names of the arguments. E.g.
task :upload, :file1, :file2 do ... end
If you have dependencies, you use :needs ...
task :upload, :file1, :file2, :needs => [:pre_upload] do ... end
To get to the args, the task lambdas get an extra argument ...
task :upload, :file1, :file2 do |t, args|
puts "File one is: #{args.file1}"
puts "File two is: #{args.file2}"
end
Also, args[:file1] will work too.

I'll get some official docs put together soon. Thanks for your
patience.
