### Compare Versions with Pre-release Labels

Source: https://github.com/phar-io/version/blob/master/README.md

Illustrates how to compare versions that include pre-release labels. It shows the usage of the Version class to determine the greater version between two versions with pre-release identifiers.

```php
$leftVersion = new PharIo\Version\Version('3.0.0-alpha.1');
$rightVersion = new PharIo\Version\Version('3.0.0-alpha.2');

$leftVersion->isGreaterThan($rightVersion); // false
$rightVersion->isGreaterThan($leftVersion); // true
```

### Parse and Comply with Version Constraints

Source: https://github.com/phar-io/version/blob/master/README.md

Demonstrates parsing version constraints using caret and tilde operators and checking if a given version complies with these constraints. It utilizes the VersionConstraintParser and Version classes.

```php
use PharIo\Version\Version;
use PharIo\Version\VersionConstraintParser;

$parser = new VersionConstraintParser();
$caret_constraint = $parser->parse( '^7.0' );

$caret_constraint->complies( new Version( '7.0.17' ) ); // true
$caret_constraint->complies( new Version( '7.1.0' ) ); // true
$caret_constraint->complies( new Version( '6.4.34' ) ); // false

$tilde_constraint = $parser->parse( '~1.1.0' );

$tilde_constraint->complies( new Version( '1.1.4' ) ); // true
$tilde_constraint->complies( new Version( '1.2.0' ) ); // false
```
