Emiliano, Great to hear that it works for you! Thanks for the valuable testing.
To avoid future confusion about this filetype I have updated git://dev.laptop.org/users/erik/image-digestor so that it refers to a 'placement control file' and produces <image file basename>.plc as output. This should make things slightly clearer semantically. Please git-pull. Erik On Wed, Dec 17, 2008 at 04:28:54PM -0200, Emiliano Pastorino wrote: > It worked.
