 - **Ready for meta-programming**: Omath use templates for common types like Vectors, Matrixes etc, to handle all types!
 - **Engine support**: Supports coordinate systems of Source, Unity, Unreal, IWEngine and canonical OpenGL.
 - **Cross platform**: Supports Windows, MacOS and Linux.
+- **Algorithms**: Has ability to scan for byte pattern with wildcards in PE files/modules, binary slices, works even with Wine apps.
