2009-11-24 Thread Todd Zullinger
Some of you might be aware that the instructions for verifying our *-CHECKSUM files on Windows have been broken since we moved to SHA256. Previously, we linked users to a sha1sum.exe built by the GnuPG project. With SHA256, we don't have that ability. Fortunately, the good folks working on MingW
