[Qgis-developer] ZX

[Tim Sutton]

Hi

Nice! That will also ease packaging and redistribution issues - we can
just create an mp3 podcast of the qgis z80 binary that people can
download and record onto their tape recorder and play back to the ZX.
Excellent stuff...

BTW you missed April Fools day by a month :-P

Regards

Tim
