-"""This is wxSlash 1.1
-
- It's the obligatory Slashdot.org headlines reader that any modern
-widget set/library must have in order to be taken seriously :-)
-
- Usage is quite simple; wxSlash attempts to download the 'ultramode.txt'
-file from http://slashdot.org, which contains the headlines in a computer
-friendly format. It then displays said headlines in a wxWindows list control.
-
- You can read articles using either Python's html library or an external
-browser. Uncheck the 'browser->internal' menu item to use the latter option.
-Use the settings dialog box to set which external browser is started.
-
- This code is available under the wxWindows license, see elsewhere. If you
-modify this code, be aware of the fact that slashdot.org's maintainer,
-CmdrTaco, explicitly asks 'ultramode.txt' downloaders not to do this
-automatically more than twice per hour. If this feature is abused, CmdrTaco
-may remove the ultramode file completely and that will make a *lot* of people
-unhappy.
-
- I want to thank Alex Shnitman whose slashes.pl (Perl/GTK) script gave me
-the idea for this applet.
-
- Have fun with it,
-
