    * Can dynamically stream the profiling data to another machine instead
      of saving it locally, which is useful for profiling on memory-constrained systems
    * Supports AMD64, ARM, AArch64 and MIPS64 architectures (where MIPS64 requires a tiny out-of-tree kernel patch for `perf_event_open`)
+   * Supports profiling of applications which use jemalloc as their allocator (only works on AMD64 with the `jemallocator` crate)
+   * Supports an embedded DSL based on [Rhai](https://rhai.rs) to allow for programmatic
+     and/or automated data analysis

 ## Enabling full debug logs
 
 By default the profiler is compiled with most of its debug logs disabled for performance reasons.
