__doc__ = """This is wxSlash 1.0
|
|
|
|
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 how 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,
|
|
