| // Package flags provides definitions for commonly used flags and where |
| // appropriate, implementations of the flag.Value interface for those flags |
| // to ensure that only valid values of those flags are supplied. Some of these |
| // flags may also be specified using environment variables directly for |
| // are documented accordingly; in these cases the command line value takes |
| // precedence over the environment variable. |
| // Flags are defined as 'groups' of related flags so that caller may choose |
| // which ones to use without having to be burdened with the full set. The |
| // groups may be used directly or via the Flags type that aggregates multiple |
| // groups. In all cases, the flags are registered with a supplied |
| // flag.FlagSet and hence are not forced onto the command line |
| // unless the caller passes in flag.CommandLine as the flag.FlagSet to use. |
| // In general, this package will be used by veyron profiles and the |
| // runtime implementations, but can also be used by any application |
| // that wants access to the flags and environment variables it supports. |
