"""Transformer Engine bindings for JAX.

This module provides JAX bindings for NVIDIA's Transformer Engine, enabling
high-performance transformer operations with mixed precision and quantization
support. It includes implementations of key transformer components like attention,
linear layers, and layer normalization, optimized for NVIDIA GPUs.

The module exports various transformer operations and utilities:
- Attention mechanisms (self-attention, cross-attention)
- Linear transformations with optional quantization
- Layer normalization operations
- Activation functions
- Softmax operations
- Sharding utilities for distributed training

All operations are designed to work seamlessly with JAX's functional programming
model and support automatic differentiation.
