+Profiling API for adding external tool instrumentation support to any project.
+This was motivated by the need to quickly add instrumentation to the ADIOS2 library without adding a build dependency, or tying to a specific measurement tool.
+The initial prototype implementation was tied to TAU, but evolved to this more generic version, which was extracted as a separate repository for testing and demonstration purposes.
