Google "ruby logger" and you get right to the RDoc documentation -
http://www.ruby-doc.org/stdlib/libdoc/logger/rdoc/index.html

Access the "logger" class and you'll get some very good documentation.

Re: errors - the standard error stream goes to STDERR, a constant ruby 
automatically creates. Normally, this goes to STDOUT - the standard 
output stream, assigned to your screen, but you can reassign it:

$stderr = File.new( 'myerrs.txt','w' )

Hope this helps...
