// Apps describe the top level application

// You create an App and set various options on that App using the "builder pattern"
|
|
//
|
|
// The options (version(), author(), about()) aren't mandatory, but recommended. There is
|
|
// another option, usage(), which is an exception to the rule. This should only be used when
|
|
// the default usage string automatically generated by clap doesn't suffice.
|
|
//
|
|
// You also set all the valid arguments your App should accept via the arg(), args(), arg_from_usage()
|
|
// and args_from_usage() (as well as subcommands via the subcommand() and subcommands() methods) which
|
|
// will be covered later.
|
|
//
|
|
// Once all options have been set, call one of the .get_matches* family of methods in order to
|
|
// start the parsing and find all valid command line arguments that supplied by the user at
|
|
// runtime. The name given to new() will be displayed when the version or help flags are used.
