- * 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
