Add lots of comments explaining things in the code. Also fix parsing of Beta updates which have hrev version numbers with an extra bit at the end, like hrev12345_67. Include architecture in the GRUB menu title, so you can tell 32 bit and 64 bit installs apart. Switch back to #!/usr/bin/sh, like all the other probes do.
