better yet, use the standard Spearfish SPOT imagery sample dataset
for the examples. (as m.eigensystem and now i.pca help page
examples do, probably others)

is there a way to change text color in MediaWiki? it might be
easier to highlight m.eigensystem output rows by color instead
of '#'s.


idea for possible google summer of code 2009 project: overhaul i.*
modules/lib for grass7. US$4.5k bounty :)
