DESCRIPTION

   FV is a viewer for binary files. It was designed to help the user analyze
   files, especially files that may contain graphical images. For example, if
   you have a large file that contains a bitmap, but you don't know where and
   what the size is, you can look at the pattern of the bytes while changing
   the width. You can also search for exact or coded strings.

   This program was actually intended for personal use, so there are many
   hidden unducumented features!
