[udig-devel] Developing a new file format plugin

[Paul Austin]

Hi Jordy,

I'm looking at several formats including GPX (GPS Exchange), SAIF and
any others I find useful, once I have them up and running I will look at
making them available to the wider community. Not sure when that we'll
be however.

Cheers,
Paul
