Sample image for the latest version of the Unix frontend patch,
see p.unofficial.patches (same subject) for details.  The POV-Ray text
streams are colored and formatted according to the following settings:

export POV_STREAM_COLORS="status=01:fatal=01;37;41:warning=37;43"
export POV_STREAM_FORMATS="all=POV> %s <POV:fatal=*** %s ***:status= "  # note the
last space

	The default wrap width is used here (i.e. the text is wrapped
when it reaches the size of the terminal window, in this case 80 chars).
A custom wrap width can be specified as e.g.:

export POV_STREAM_WRAP_WIDTH=120

	All of these environment variables can be replaced by equivalent
command-line options when runing povray.  For instance, the above settings
may be specified as:

povray scene.ini \
   --pov-stream-colors="status=01:fatal=01;37;41:warning=37;43" \
   --pov-stream-formats="all=POV> %s <POV:fatal=*** %s ***:status= " \
   --pov-stream-wrap-width=120

	- NC
