"""IronLicensing SDK for Python.

Software licensing and activation SDK.

Example:
    >>> import ironlicensing
    >>>
    >>> # Initialize
    >>> ironlicensing.init("pk_live_xxxxx", "my-app")
    >>>
    >>> # Validate a license
    >>> result = ironlicensing.validate("IRON-XXXX-XXXX-XXXX-XXXX")
    >>> if result.valid:
    ...     print("License is valid!")
    >>>
    >>> # Check features
    >>> if ironlicensing.has_feature("premium"):
    ...     print("Premium features enabled")
