Constructor Details

#initialize(options = {}) ⇒ Maid

Make a new Maid, setting up paths for the log and trash.

Sane defaults for a log and trash path are set for Mac OS X, but they can easily be overridden like so:

Maid::Maid.new(:log_device => '/home/username/log/maid.log', :trash_path => '/home/username/.local/share/Trash/files/')
