+"""IPython extension to reload modules before executing user code.
+
+``autoreload`` reloads modules automatically before entering the execution of
+code typed at the IPython prompt.
+
+This makes for example the following workflow possible:
+
+.. sourcecode:: ipython
+
+   In [1]: %load_ext autoreload
+
+   In [2]: %autoreload 2
+
+   In [3]: from foo import some_function
+
+   In [4]: some_function()
+   Out[4]: 42
+
+   In [5]: # open foo.py in an editor and change some_function to return 43
+
+   In [6]: some_function()
+   Out[6]: 43
+
+The module was reloaded without reloading it explicitly, and the object
+imported with ``from foo import ...`` was also updated.
+
+Usage
+=====
+
+The following magic commands are provided:
+
+``%autoreload``
+
+    Reload all modules (except those excluded by ``%aimport``)
+    automatically now.
+
+``%autoreload 0``
+
+    Disable automatic reloading.
+
+``%autoreload 1``
+
+    Reload all modules imported with ``%aimport`` every time before
+    executing the Python code typed.
+
+``%autoreload 2``
+
+    Reload all modules (except those excluded by ``%aimport``) every
+    time before executing the Python code typed.
+
+``%aimport``
+
+    List modules which are to be automatically imported or not to be imported.
+
+``%aimport foo``
+
+    Import module 'foo' and mark it to be autoreloaded for ``%autoreload 1``
+
+``%aimport foo, bar``
+
+    Import modules 'foo', 'bar' and mark them to be autoreloaded for ``%autoreload 1``
+
+``%aimport -foo``
+
+    Mark module 'foo' to not be autoreloaded.
+
+Caveats
+=======
+
+Reloading Python modules in a reliable way is in general difficult,
+and unexpected things may occur. ``%autoreload`` tries to work around
+common pitfalls by replacing function code objects and parts of
+classes previously in the module with new versions. This makes the
+following things to work:
+
+- Functions and classes imported via 'from xxx import foo' are upgraded
+  to new versions when 'xxx' is reloaded.
+
+- Methods and properties of classes are upgraded on reload, so that
+  calling 'c.foo()' on an object 'c' created before the reload causes
+  the new code for 'foo' to be executed.
+
+Some of the known remaining caveats are:
+
+- Replacing code objects does not always succeed: changing a @property
+  in a class to an ordinary method or a method to a member variable
+  can cause problems (but in old objects only).
+
+- Functions that are removed (eg. via monkey-patching) from a module
+  before it is reloaded are not upgraded.
+
+- C extension modules cannot be reloaded, and so cannot be autoreloaded.

+
+        * ``%store``          - Show list of all variables and their current
+                                values
+        * ``%store spam bar`` - Store the *current* value of the variables spam
+                                and bar to disk
+        * ``%store -d spam``  - Remove the variable and its value from storage
+        * ``%store -z``       - Remove all variables from storage
+        * ``%store -r``       - Refresh all variables, aliases and directory history
+                                from store (overwrite current vals)
+        * ``%store -r spam bar`` - Refresh specified variables and aliases from store
+                                   (delete current val)
+        * ``%store foo >a.txt``  - Store value of foo to new file a.txt
+        * ``%store foo >>a.txt`` - Append value of foo to file a.txt
+
+        It should be noted that if you change the value of a variable, you
+        need to %store it again if you want to persist the new value.
+
+        Note also that the variables will need to be pickleable; most basic
+        python types can be safely %store'd.
+
+        Also aliases can be %store'd across sessions.
+        To remove an alias from the storage, use the %unalias magic.
