+.SH DESCRIPTION
+.PP
+This program is part of
+.BR "Netpbm" (1)\c
+\&.
+.PP
+\fBrletopnm\fP converts Utah Raster Toolkit RLE image files to PNM
+image files. \fBrletopnm\fP handles four types of RLE files:
+Grayscale (8 bit data, no color map), Pseudocolor (8 bit data with a
+color map), Truecolor (24 bit data with color map), and Directcolor
+(24 bit data, no color map). \fBrletopnm\fP generates a PPM file for
+all these cases except for the Grayscale file, for which
+\fBrletopnm\fP generates a PGM file.
+.PP
+\fIrlefile\fP is the RLE input file. If it is absent or \fB-\fP,
+the input comes from Standard Input.
+
+.UN options
+.SH OPTIONS
+
+
+.TP
+\fB--alphaout=\fP\fIalpha-filename\fP
+\fBrletopnm \fP creates a PGM (portable graymap) file containing the
+transparency channel values in the input image. If the input image doesn't
+contain an transparency channel, the \fIalpha-filename\fP file contains all
+zero (transparent) transparency values. If you don't specify
+\fB--alphaout\fP, \fBrletopnm\fP does not generate a transparency file,
+and if the input image has a transparency channel, \fBrletopnm\fP simply
+discards it.
+.sp
+If you specify \fB-\fP as the filename, \fBrletopnm\fP writes the
+transparency output to Standard Output and discards the image.
+.sp
+See
+.BR "pamcomp" (1)\c
+\& for one way to use
+the transparency output file.
+
+.TP
+\fB--verbose\fP
+This option causes \fBrletopnm \fP to operate in verbose mode.
+It prints messages about what it's doing, including the contents of
+the RLE image header, to Standard Error.
+
+.TP
+\fB--headerdump\fP
+This option causes \fBrletopnm\fP to operate in header dump mode.
+It prints the contents of the RLE image header to Standard Error, but
+does not produce any other output.
+
+
+
+.UN examples
+.SH EXAMPLES
+
+
+.IP \(bu
+While running in verbose mode, convert lenna.rle to PPM format and
+store the resulting image as lenna.ppm:
+
+.nf
+\f(CW
+ rletopnm --verbose lenna.rle >lenna.ppm
+\fP
+.fi
+
+.IP \(bu
+Dump the header information of the RLE file called file.rle:
+
+.nf
+\f(CW
+ rletopnm --headerdump file.rle
+\fP
+.fi
+
+.IP \(bu
+Convert RLE file dart.rle to PPM format as dart.ppm. Store the
+transparency channel of dart.rle as dartalpha.pgm (if dart.rle doesn't have
+a transparency channel, store a fully transparent transparency mask as
+dartalpha.pgm):
+
+.nf
+\f(CW
+ rletopnm --alphaout=dartalpha.pgm dart.rle >dart.ppm
