+
+Fetch, configure, build, and install dependencies ("ingredients") for a CMake project
+in a local and repeatable development environment.
+
+Usage: $0 [OPTIONS]
+
+where OPTIONS are:
+
+-a
+-r RECIPE
+-e INGREDIENT
+-i INGREDIENT
+-d BUILD_DIR (=${build_dir})
+-p INGREDIENTS_DIR (=${build_dir}/_cooking/installed)
+-t BUILD_TYPE (=${build_type})
+-g GENERATOR (=${generator})
+-s VAR=VALUE
+-f EXPORT_DIR
+-l
+-h
+
+By default, cmake-cooking reads a file called `cooking_recipe.cmake`.
+
+If neither [-i] nor [-e] are specified with a recipe ([-r]), then all ingredients of the recipe
+will be fetched and built.
+
+[-i] and [-e] are mutually-exclusive options: only provide one.
+
+Option details:
+
+-a
+
+    Invoke 'cooking.sh' with the arguments that were provided to it last time, instead
+    of the arguments provided.
+
+-r RECIPE
+
+    Instead of reading the recipe in a file called `cooking_recipe.cmake`, follow the recipe
+    in the named file.
+
+    If the recipe file is a relative path, it is interpretted relative to the source directory
+    of the project.
+
+-e INGREDIENT
+
+    Exclude an ingredient from a recipe. This option can be supplied many times.
+
+    For example, if a recipe consists of 'apple', 'banana', 'carrot', and 'donut', then
+
+        ./cooking.sh -r dev -e apple -e donut
+
+    will prepare 'banana' and 'carrot' but not prepare 'apple' and 'donut'.
+
+    If an ingredient is excluded, then it is assumed that all ingredients that depend on it
+    can satisfy that dependency in some other way from the system (ie, the dependency is
+    removed internally).
+
+-i INGREDIENT
+
+   Include an ingredient from a recipe, ignoring the others. This option can be supplied
+   many times.
+
+   Similar to [-e], but the opposite.
+
+   For example, if a recipe consists of 'apple', 'banana', 'carrot', and 'donut' then
+
+       ./cooking.sh -r dev -i apple -i donut
+
+   will prepare 'apple' and 'donut' but not prepare 'banana' and 'carrot'.
+
+   If an ingredient is not in the "include-list", then it is assumed that all
+   ingredients that are in the list and which depend on it can satisfy that dependency
+   in some other way from the system.
+
+-d BUILD_DIR (=${build_dir})
+
+   Configure the project and build it in the named directory.
+
+-p INGREDIENTS_DIR (=${build_dir}/_cooking/installed)
+
+   Install compiled ingredients into this directory.
+
+-t BUILD_TYPE (=${build_type})
+
+   Configure all ingredients and the project with the named CMake build-type.
+   An example build type is "Release".
+
+-g GENERATOR (=${generator})
+
+    Use the named CMake generator for building all ingredients and the project.
+    An example generator is "Unix Makfiles".
+
+-s VAR=VALUE
+
+   Set an environmental variable 'VAR' to the value 'VALUE' during the invocation of CMake.
+
+-f EXPORT_DIR
+
+   If provided, and the project is successfully configured, then the tree of installed ingredients
+   is exported to this directory (the actual files: not symbolic links).
+
+   This option requires rsync.
+
+   This may be useful for preparing continuous integration environments, but it is not
+   recommended for distribution or release purposes (since this would be counter
+   to the goal of cmake-cooking).
+
+-l
+
+    Only list available ingredients for a given recipe, and don't do anything else.
+
+-h
+
+    Show this help information and exit.
