Convert a .daa File to a .iso in Linux using Poweriso

Often times I still come across .daa files. Although we can burn these to disc as a image I prefer the .iso format.

I decided to make a quick post on converting these in Linux.

Both of these utilities allow secure communication with remote computers. Below I describe adding them to an existing Cygwin Windows 7 installation.
