*
* fbcat.c:
* Convert an image from one format to another. Input image type
* is determined by magic number. Output is specified by argument.
* Note that the ascpect ratio, size and number of colors is not
* changed, and that some conversions (such as grayscale to bitmap
* or color to gray require more processing than fbcat can do.
* For these transformations you must use other programs like
* clr2gray, gray2clr, fbhalf, and fbsample.
*
* USAGE
* % fbcat [ -t'title' -c'credits' ] [ -<type> ] [ image ] > image
