+Recursive Modules
+``````````````````
+
+In some cases, it is desirable to load not just a module, but also all
+the modules it depends on. This is not required for most modules
+because Spack builds binaries with RPATH support. However, not all
+packages use RPATH to find their dependencies: this can be true in
+particular for Python extensions, which are currently *not* built with
+RPATH.
+
+Modules may be loaded recursively with the command:
+
+.. code-block:: sh
+
+ $ module load `spack module tcl --dependencies <spec>...
+
+More than one spec may be placed on the command line here.
+
+Module Comamnds for Shell Scripts
+``````````````````````````````````
+
+Although Spack is flexbile, the ``module`` command is much faster.
+This could become an issue when emitting a series of ``spack load``
+commands inside a shell script. By adding the ``--shell`` flag,
+``spack module find`` may also be used to generate code that can be
+cut-and-pasted into a shell script. For example:
+
+.. code-block:: sh
+
+ $ spack module find tcl --dependencies --shell py-numpy git

+Local Default Cache
+----------------------------
+
+Spack caches resources that are downloaded as part of installs. The cache is
+a valid spack mirror: it uses the same directory structure and naming scheme
+as other Spack mirrors (so it can be copied anywhere and referenced with a URL
+like other mirrors). The mirror is maintained locally (within the Spack
+installation directory) at :file:`var/spack/cache/`. It is always enabled (and
+is always searched first when attempting to retrieve files for an installation)
+but can be cleared with :ref:`purge <spack-purge>`; the cache directory can also
+be deleted manually without issue.
+
+Caching includes retrieved tarball archives and source control repositories, but
+only resources with an associated digest or commit ID (e.g. a revision number
+for SVN) will be cached.
