"""QASM parser exceptions module.

This module defines custom exceptions for OpenQASM 2.0 parsing,
including errors for unsupported gates and register-related issues.

Key exports:
    NotSupportedGateError: Exception for unsupported quantum gates.
    RegisterNotFoundError: Exception for missing quantum/classical registers.
    RegisterOutOfRangeError: Exception for register index out of bounds.
    RegisterDefinitionError: Exception for invalid register definitions.
