I'm wondering if/when the silvermoon sources for imgtool will be published.  According to version 1.0 of imgtool (http://files.chumby.com/source/ironforg … 1.0.tar.gz) it is under GPL license, and version 1.22 is included in the infocast firmware.  I'm hoping that this is just an oversight, and the imgtool 1.22 sources will be posted to the sources page soon.
