R: [Qgis-user] raster support of JP2

[John Callahan]

Thank you Marco for the instructions.  This is great and should help me 
with other similar questions as well.

I am surprised by the amount of work it takes to add support for JP2 or 
similar format....nothing seems too complex, just more steps than I 
anticipated.  It's understandable though.  This is fine with me since I 
was planning to start building several of these packages directly from 
source anyway (I've been downloading Win binaries thus far.)
