Updated docs for converter.

converter/README.converter

 The converter is a command line utility that will convert from COLLADA
 to the form that the sample JavaScript scene loader (in
 samples/o3djs/serialization.js) can read.
 
 It is able to read COLLADA files as either DAE text files (and
 associated asset files in subdirectories), or as part of a ZIP archive
-(or KMZ file).  It outputs a gzip-compressed tar archive (.tgz) which
-contains a JSON file and any associated assets (textures, shaders,
-etc.) from the source COLLADA model.  By default we don't use the .tgz
-extension, as it can cause problems with some webservers; we put .o3dtgz on
-instead.
+(or KMZ file).  By default it outputs a gzip-compressed tar archive
+(.tgz) which contains a JSON file and any associated assets (textures,
+shaders, etc.) from the source COLLADA model.  By default we don't use
+the .tgz extension, as it can cause problems with some webservers; we
+put .o3dtgz on instead. The converter can optionally output a set of
+flat files into a directory, which is the layout compatible with the
+WebGL implementation of O3D.
 
 In order to run the converter on Windows, you need the DirectX SDK installed.
 Installing it requires administrator privileges.  You can get it here:

 The command line arguments are as follows:
 
 Usage: o3dConverter.exe [--base-path=<path>]
                         [--up-axis=x,y,z]
                         [--no-condition]
                         [--pretty-print]
+                        [--no-binary]
+                        [--no-archive]
+                        [--convert-dds-to-png]
+                        [--convert-cg-to-glsl]
                         <infile.dae> [ <outfile> ]
 
 --base-path=<path>: This specifies the path elements to remove from
                     the beginning of the filenames placed into the
                     .o3dtgz file (to avoid including sensitive paths in
                     the .o3dtgz file).
 
 --up-axis=x,y,z: This specifies the up-axis for the resulting model,
                  if you wish it to be different from the axis in the
                  COLLADA file.
 
 --pretty-print: This simply formats the JSON file in the resulting
                 .o3dtgz file to be human readable, instead of compacted
                 into one line.
 
 --no-condition: This will prevent conditioning of the shaders from
                 COLLADA form to the form expected by O3D.  [This is
                 useful only for pre-release data conditioned before
                 the converter existed.]
 
+The following four command line options are useful when converting
+assets for the WebGL implementation of O3D:
+
+--no-binary: Buffers, skins and curves will be written directly into the
+             scene.json rather than into separate binary files.
+
+--no-archive: Don't make a gzipped tar file, just flat files. Still
+              takes the name of an archive file; for archive.o3dtgz,
+              creates directory named archive/ and writes files inside.
+
+--convert-dds-to-png: Convert all DDS textures to PNGs. For cube map
+                      textures, writes six separate PNGs with suffixes
+                      _posx, _negx, etc.
+
+--convert-cg-to-glsl: Convert shaders using an external tool. Requires
+                      python on PATH and either NVIDIA Cg toolkit
+                      installed or cgc{.exe} in same directory as
+                      converter.
+
 <infile.dae|infile.zip|infile.kmz>: This is the input file in one of
                                     ZIP, KMZ, or DAE formats.  The
                                     DAE format expects to find assets
                                     relative to the .dae file.
 
 <outfile>: An optional argument giving the name of the
            gzip-compressed tar archive output file.  By default
            this has the same basename as the input file, and has the extension
            .o3dtgz.
