-/// The abstract representation of a command line argument. Used to set all the options and

-///
-/// There are two methods for constructing [`Arg`]s, using the builder pattern and setting options
-/// manually, or using a usage string which is far less verbose but has fewer options. You can also
-/// use a combination of the two methods to achieve the best of both worlds.

-/// Family of related [arguments].
-///
-/// By placing arguments in a logical group, you can create easier requirement and
-/// exclusion rules instead of having to list each argument individually, or when you want a rule
-/// to apply "any but not all" arguments.
-///
-/// For instance, you can make an entire `ArgGroup` required. If [`ArgGroup::multiple(true)`] is
-/// set, this means that at least one argument from that group must be present. If
-/// [`ArgGroup::multiple(false)`] is set (the default), one and *only* one must be present.
-///
-/// You can also do things such as name an entire `ArgGroup` as a [conflict] or [requirement] for
-/// another argument, meaning any of the arguments that belong to that group will cause a failure
-/// if present, or must be present respectively.
-///
-/// Perhaps the most common use of `ArgGroup`s is to require one and *only* one argument to be
-/// present out of a given set. Imagine that you had multiple arguments, and you want one of them
-/// to be required, but making all of them required isn't feasible because perhaps they conflict
-/// with each other. For example, lets say that you were building an application where one could
-/// set a given version number by supplying a string with an option argument, i.e.
-/// `--set-ver v1.2.3`, you also wanted to support automatically using a previous version number
-/// and simply incrementing one of the three numbers. So you create three flags `--major`,
-/// `--minor`, and `--patch`. All of these arguments shouldn't be used at one time but you want to
-/// specify that *at least one* of them is used. For this, you can create a group.
-///
-/// Finally, you may use `ArgGroup`s to pull a value from a group of arguments when you don't care
-/// exactly which argument was actually used at runtime.
-///
-/// # Examples
-///
-/// The following example demonstrates using an `ArgGroup` to ensure that one, and only one, of
-/// the arguments from the specified group is present at runtime.
-///
-/// ```rust
-/// # use clap_builder as clap;
-/// # use clap::{Command, arg, ArgGroup, error::ErrorKind};
-/// let result = Command::new("cmd")
-///     .arg(arg!(--"set-ver" <ver> "set the version manually"))
-///     .arg(arg!(--major           "auto increase major"))
-///     .arg(arg!(--minor           "auto increase minor"))
-///     .arg(arg!(--patch           "auto increase patch"))
-///     .group(ArgGroup::new("vers")
-///          .args(["set-ver", "major", "minor", "patch"])
-///          .required(true))
-///     .try_get_matches_from(vec!["cmd", "--major", "--patch"]);
-/// // Because we used two args in the group it's an error
-/// assert!(result.is_err());
-/// let err = result.unwrap_err();
-/// assert_eq!(err.kind(), ErrorKind::ArgumentConflict);
-/// ```
-///
-/// This next example shows a passing parse of the same scenario
-/// ```rust
-/// # use clap_builder as clap;
-/// # use clap::{Command, arg, ArgGroup, Id};
-/// let result = Command::new("cmd")
-///     .arg(arg!(--"set-ver" <ver> "set the version manually"))
-///     .arg(arg!(--major           "auto increase major"))
-///     .arg(arg!(--minor           "auto increase minor"))
-///     .arg(arg!(--patch           "auto increase patch"))
-///     .group(ArgGroup::new("vers")
-///          .args(["set-ver", "major", "minor","patch"])
-///          .required(true))
-///     .try_get_matches_from(vec!["cmd", "--major"]);
-/// assert!(result.is_ok());
-/// let matches = result.unwrap();
-/// // We may not know which of the args was used, so we can test for the group...
