+"""
+
+This is an extemely simple and crude example of using
+a KHTMLPart - I put it together mostly to make sure
+the openURL method worked correctly after some modifications
+done in KParts::ReadOnlyPart. It took exactly four lines
+added to a basic PyKDE app framework to display a URL
+via the 'net:
+
+ self.w = KHTMLPart (self, "HTMLPart", self);
+ self.w.openURL (KURL ("http://www.kde.org"));
+ self.w.view ().setGeometry (30, 55, 500, 400);
+ self.w.show ();
+
+(Actually 5 lines if you count the 'import' line)
+
+You can play around with the commented out lines or add
+additional code to make this do something useful. The
+.rc for khtnmlpart (sorry, I never looked it up), doesn't
+seem to provide much help. Also, to follow links, you
+probably need to connect some signals to slots. I
+haven't tried it, but this should work with a plain
+KMainWindow or other widget too.
+
+The KDE website also incorporates gifs, jpegs, and
+I believe CSS too. Playing around with some other
+sites, it appears the font defaults could use some
+improvement.
+
+NOTE!!! For this to work, you (obviously) need to have
+a route to the internet established or specify a local
+URL - PyKDE/KDE will take care of everything else.
+
+Perceptive users will notice the KHTMLPart code is
+lifted from the KDE classref.
