[Olsr-dev] Including GPS information

[Sven-Ola Tücke]

Hey,

I sometimes forget, that there is still an ancient O.S arouce named windows. 
With a user base not very used to edit config files AFAIK. 

If you prefer the gui programme, you may need to save the config file 
e.g. "Default.olsr", edit that manually and restart. Or add the approriate 
GUI controls to GUI and re-compile. 

As a tip: for a tight system integration - as it's standard on UNIX-like 
O.Ses - you need to add olsrd as windows service anyhow (see 
http://support.microsoft.com/kb/137890 for an more in depth explanation)

Read the source, luke!
