+"""A generated module for Book functions
+
+This module has been generated via dagger init and serves as a reference to
+basic module structure as you get started with Dagger.
+
+Two functions have been pre-created. You can modify, delete, or add to them,
+as needed. They demonstrate usage of arguments and return types using simple
+echo and grep commands. The functions can be called from the dagger CLI or
+from one of the SDKs.
+
+The first line in this comment block is a short description line and the
+rest is a long description with more detail on the module's purpose or usage,
+if appropriate. All modules should have a short description.
