 .SH NAME
-png2swf - convert one or more PNG pictures to swf
+png2swf - Takes a number of png files and converts them to a swf movie, one
+picture per frame.
+
 .SH Synopsis
 .B png2swf [-X width] [-Y height] [-o file.swf] [-r rate] file1.png [file2.png...]
+
 .SH DESCRIPTION
-Takes a number of png files and converts them to a swf movie, one
-picture per frame.
+This tools converts png image files into an SWF animation. It takes any
+number of input pictures, and converts them to SWF one-by-one, where every
+converted picture is a seperate frame in the target SWF. 
 .PP
-(SWF files are animation files which can be displayed in Web Browsers using
-the Flash Plugin)
+The way the
+images are encoded in SWF is very similar to PNG (in that a zlib-based, lossless
+compression algorithm is used).

 .SH OPTIONS
 .TP
-\fB\-h\fR, \fB\-\-help\fR
-Print short help message and exit
+\fB\-r\fR, \fB\-\-rate\fR \fIframerate\fR
+    Set movie framerate (frames per second)
 .TP
-\fB\-V\fR, \fB\-\-version\fR
-Print version info and exit
+\fB\-o\fR, \fB\-\-output\fR \fIfilename\fR
+    Explicitly specify output file. (Otherwise, output will go to stdout / output.swf)
 .TP
-\fB\-X\fR, \fB\-\-width\fR \fIscale\fR
-Force movie width to \fIscale\fR (default: autodetect)
+\fB\-j\fR, \fB\-\-jpeg\fR \fIquality\fR
+    Generate a lossy jpeg bitmap inside the SWF, with a given quality (1-100)
 .TP
-\fB\-Y\fR, \fB\-\-height\fR \fIscale\fR

+\fB\-z\fR, \fB\-\-zlib\fR \fIzlib\fR        
+    Use Flash MX (SWF 6) Zlib encoding for the output. The resulting SWF will be
