/*
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.
Note that any passed value must contain no whitespace.
