/*
These values should be filled in at build time using the `-X` option[1] to the
Go linker (probably via `-ldflags` option to `go build` -- like `-ldflags "-X var1 abc -X var2 xyz"`).
[1]: http://golang.org/cmd/ld/
Without those build flags, the build info in the notice will simply be empty strings.
Suggestions for how to fill in the values will be given for each variable.
