.SH SYNOPSIS
.B rastorle

.I outfile
] [ 
.I infile.ras
] 
.SH DESCRIPTION
.I Rastorle
converts a sun raster file to a file in the
Utah Raster Toolkit 
.IR RLE (5)
format.  It understands both the original unencoded format and the
"type 2" (run length encoded) format raster files.  Since Sun raster
files and RLE images disagree on where the origin is, the program
automatically flips the image.
.SH OPTIONS
.TP
.I infile.ras
The input sun raster will be read from this file, otherwise, input will
be taken from stdin.
.TP
.B \-a
If specified, an alpha channel will be "faked".  That is, the alpha
channel will be zero wherever the input is black (0), and 255
elsewhere.
.BI \-o " outfile"
If specified, output will be written to this file, otherwise it will
go to stdout.
