+A pluggable, mockable process invocation abstraction for Dart.
+
+## What's this?
+
+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` requires processes to be started with
+[ProcessManager], which allows for easy mocking and testing of code that
+spawns processes in a hermetic way.
