NFOViewer is a small utility application for viewing .nfo files.
Certainly not the most robust nfo viewer ever, but likely the best on the mac. A seperate font download is reqired for the program to operate (mentioned in readme).
*from wikipedia
NFO files usually contain release information about a software program and are commonly associated with software piracy groups. A typical modern day warez NFO file is elaborate and highly decorated, donning a large ASCII art logo at the top with various software release and warez group information below.
