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.</p>
<p>For instance, you can make an entire <code>ArgGroup</code> required. If <ahref="./struct.ArgGroup.html#method.multiple"><code>ArgGroup::multiple(true)</code></a> is
set, this means that at least one argument from that group must be present. If
[<code>ArgGroup::multiple(false)</code>] is set (the default), one and <em>only</em> one must be present.</p>
<p>You can also do things such as name an entire <code>ArgGroup</code> as a <ahref="./struct.Arg.html#method.conflicts_with">conflict</a> or <ahref="./struct.Arg.html#method.requires">requirement</a> for
another argument, meaning any of the arguments that belong to that group will cause a failure
if present, or must present respectively.</p>
<p>Perhaps the most common use of <code>ArgGroup</code>s is to require one and <em>only</em> 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.
<code>--set-ver v1.2.3</code>, you also wanted to support automatically using a previous version number
and simply incrementing one of the three numbers. So you create three flags <code>--major</code>,
<code>--minor</code>, and <code>--patch</code>. All of these arguments shouldn't be used at one time but you want to
specify that <em>at least one</em> of them is used. For this, you can create a group.</p>
<p>Finally, you may use <code>ArgGroup</code>s to pull a value from a group of arguments when you don't care
exactly which argument was actually used at runtime.</p>
<spanclass="comment">// we could also alternatively check each arg individually (not shown here)</span></pre></div>
