From the developer:
CmdRef is an offline, searchable Windows CMD dictionary. It is not an emulator and does not allow you to type Windows CMD commands on your Mac. CmdRef is a handy learning tool for those new to command prompt, and an excellent, portable dictionary for every expert too. CmdRef's clean, modern design was created with an emphasis on ease of use and reliability.
