+# Process
+
+A generic process invocation abstraction for Dart.
+
+Like `dart:io`, `package:process` supplies a rich, Dart-idiomatic API for
+spawning OS processes.
+
+Unlike `dart:io`, `package:process`:
+
+- Can be used to implement custom process invocation backends.
+- Comes with a record-replay implementation out-of-the-box, making it super
+  easy to test code that spawns processes in a hermetic way.
