	PNGScan is a small Freeware program for analyzing and displaying
the structure of a PNG picture file.  It can be used for error checking, or
to find out exactly what a graphics application puts in its PNG files.

	For those of you who don't know this, PNG (pronounced 'Ping') is a
replacement for the now obsolete GIF format.  It has all the features GIF
has, with the addition of a truecolor mode.

	PNGScan displays all chunks in a PNG file (and will warn if it
finds anything suspicious), and can interpret the following:
	- IHDR   Header with all kinds of information
	- PLTE   Palette entries.  PNGScan will show the number of colors in
                 the palette.
	- tEXt   Various comments, such as author, application used...


Usage:
	PNGScan can only be used from Shell.
