I tried to do this in Ruby as an exercise, and it came out rather 
inelegant. Anyone on the list know the language and have a better approach?

# can't rename directories at the same time as files
# eg: find gives us /FOO/BAR but now it's at /foo/BAR. error!
# the order of directories is important for the same reason

require 'fileutils'
require 'find'
require 'ftools'
directories = Array.new
Find.find('/path/to/start/renaming/at') do |path|
   basename = File.basename(path)
   if basename.match('[A-Z]')
     if File.directory?(path)
       directories.unshift(path)
     else
       FileUtils.mv(path, path.gsub(basename,basename.downcase))
     end
   end
end
directories.each do |path|
   basename = File.basename(path)
   FileUtils.mv(path, path.gsub(basename,basename.downcase))
end
