+Feature: packaging
+    As an author
+    I want to package my book and other files into a single archive
+    So I can easily distribute it over the internet
+
+    Background:
+        Given a basic project
+
+    Scenario: compressing book
+        When I successfully run `rpub package`
+        Then a file named "untitled_book.zip" should exist
+        And the archive "untitled_book.zip" should contain file "untitled-book-0.0.0.epub"
+
+    Scenario: custom package filename
+        Given the default "config.yml" file with "package_file" set to "my_book.zip"
+        When I successfully run `rpub package`
+        Then a file named "my_book.zip" should exist
+
+    Scenario: uncompiled book
+        When I successfully run `rpub package`
+        Then a file named "untitled-book-0.0.0.epub" should exist
+
+    Scenario: help
+        When I successfully run `rpub package -h`
+        Then the output should contain "Compile your ebook to an ePub file and package it into an archive"
+
+    Scenario: additional files
+        When I successfully run `rpub package`
+        Then a file named "untitled_book.zip" should exist
+        And the archive "untitled_book.zip" should contain file "README.md"
