+// Package memcache provides an example of a memcache client compiled to
+// GOOS=wasip1.
+//
+// The test uses https://pkg.go.dev/github.com/bradfitz/gomemcache/memcache and
+// interacts with a memcache server on localhost:11211. The docker-compose.yml
+// file in the parent directory may be used to start a memcache server to run
+// the test against.
+//
+// Note that at this time, the dependency is changed to https://github.com/mar4uk/gomemcache
+// in order to get the changes from https://github.com/bradfitz/gomemcache/pull/158,
+// which is required to customize the dial function.
+//
+// When compiling to other targets than GOOS=wasip1, importing this package has
+// no effect.
