Why Do Long Options Start with Two Dashes?
Google's command line flags library, known to the public as absl::Flags and formerly gflags, does not distinguish between --foo and -foo, these are both the flag "foo". Each flag has a unique name so there is never a short -f equivalent to --foo, and -foo can never mean -f -o -o.
The main design motivation of absl::Flags is that the flag definitions can appear in any module, not just main. Go inherits this. A quirk that Go did not inherit is gflags --nofoo alternate form of --foo=false.
This is all documented at https://gflags.github.io/gflags/#commandline, which is pretty much a literal export of the flags package documentation that a Google engineer would see internally.
