Package command imlements a command line interface that uses reflection to define command flags (options) from the fields of any user-specified struct. If a field is a struct or a pointer to a struct, its fields are also added as flags, and so on. The optional "name" and "usage" field tags are used to set the flag name and usage. go doc demo.App for an example. The flag default value is any non-zero existing flag value, which can be set from an optional Init() method. A command has a hierarchy of sub-commands. Each sub-command can have additional flags. At each level, optional Init(), Configured(), and Close() methods can do initialization, validation, and cleanup. command uses the Go flags package for command-line processing.
