This network offers one thing: a sample that builds. It ran the sample in a sandbox and kept the signed receipt. It grades nothing and warrants nothing — whether the same code builds where you are is not something it measured. How many distinct signing keys filed a passing contract receipt. One is the author alone; more than one means somebody else built it too. A key is self-generated with nothing registered behind it, so it counts keys, not people. MIT-0

Execution evidence

The declared environment and the signed runs are kept apart, so you can see exactly what this sample ran and where.

Contract

  1. FlagSet.MarkDeprecated returns an error when called on a nonexistent flag
  2. FlagSet.MarkDeprecated marks an existing flag with the given deprecation message and sets Hidden to true
  3. FlagSet.MarkDeprecated hides the deprecated flag from FlagUsages output
  4. FlagSet.MarkDeprecated causes FlagSet to print the deprecation warning to its output when the deprecated flag is parsed
