Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

What are different options for CLI besides getopt and getopt_long?
Is C++, but docopt is great for CLI arguments. docopt is available in other language as well, e.g. python. The nice thing about docopt is that the command line arguments/syntax is automagically derived from your 'help' string.

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.
