#### Version Format
The package version includes the git commit hash directly in the version
string for development builds:
- **Release version**: `0.7.0`
- **Development version**: `0.7.0.dev36+g6e2360d69` (includes short
commit hash)
- **Development with uncommitted changes**:
`0.7.0.dev36+g6e2360d69.dirty`
#### Checking Version Information
After installation, you can check the version information in several
ways:
**From Python:**
```python
import mscclpp
# Access individual attributes
print(f"Version: {mscclpp.__version__}") # Full version with commit
Version: 0.7.0.dev36+g6e2360d69
# Get as dictionary
mscclpp.version()
{'version': '0.7.0.dev46+gb0d27c58f', 'base_version': '0.7.0', 'git_commit': 'b0d27c58f'}
```
#### Version Information Details
The version tracking captures:
- **Package Version** (`mscclpp.__version__`): Full version string
including git commit (e.g., `0.7.0.dev36+g6e2360d69`)
This information is embedded during the package build process and
remains accessible even after distribution, making it easier to debug
issues and ensure reproducibility.

* Let CMake read version numbers from the `VERSION` file.
* Upgrade dlpack and drop `CMAKE_POLICY_VERSION_MINIMUM`.
* Do not install dlpack.
* Add license files in the wheel and exclude `*.cpp` files.
For mscclpp, to use nvls we require the buffer is allocated by
mscclpp::GpuBuffer. Due to cupy doesn't support bfloat16 yet, we export
the raw buffer to dlpack format.
User can use this feature to create buffer with type supported by
pytorch
```python
buffer = RawGpuBuffer(1024 * 2) # 2 for bfloat16
dl_pack = buffer.to_dlpack(str(torch.bfloat16))
tensor = torch.utils.dlpack.from_dlpack(dl_pack)
```
* Let all CMake option names start with `MSCCLPP_`
* Explain the `MSCCLPP_BUILD_PYTHON_BINDINGS` option in readme

Introduces a mscclpp.get_include() in the Python module.
The extension module is now named _mscclpp so that we can have
Python code in the mscclpp module.
Also does some miscellaneous cleanup.
