Subject: Add md5sum and sha1 commands...
X-Git-Tag: v2009.11-rc1~225^2~41
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=02c9aa1d41f73fdcf8383a36cc0cbbfaf952855d;p=oweals%2Fu-boot.git

Add md5sum and sha1 commands...

Now that we have sha1 and md5 in lib_generic, allow people to use
them on the command line, for checking downloaded files.
