--option <arg>,-o <arg>. -
Condensed short-form options:

Automatic
--helpand--versionflags. -
Support for multivalued options.
-
Support for git-style command interfaces with arbitrarily-nested commands.
Example
# use arguably::ArgParser;
let mut parser = ArgParser::new()
.helptext("Usage: foobar...")
.version("1.0")
.flag("foo f")
.option("bar b");
if let Err(err) = parser.parse() {
err.exit();
}
if parser.found("foo").unwrap() {
println!("Found --foo/-f flag.");
}
if let Some(value) = parser.value("bar").unwrap() {
println!("Found --bar/-b option with value: {}", value);
}
for arg in parser.args() {
println!("Arg: {}", arg);
}
