+"""SCons.Action
+
+This encapsulates information about executing any sort of action that
+can build one or more target Nodes (typically files) from one or more
+source Nodes (also typically files) given a specific Environment.
+
+The base class here is ActionBase.  The base class supplies just a few
+OO utility methods and some generic methods for displaying information
+about an Action in response to the various commands that control printing.
+
+A second-level base class is _ActionAction.  This extends ActionBase
+by providing the methods that can be used to show and perform an
+action.  True Action objects will subclass _ActionAction; Action
+factory class objects will subclass ActionBase.
+
+The heavy lifting is handled by subclasses for the different types of
+actions we might execute:
+
+    CommandAction
+    CommandGeneratorAction
+    FunctionAction
+    ListAction
+
+The subclasses supply the following public interface methods used by
+other modules:
+
+    __call__()
+        THE public interface, "calling" an Action object executes the
+        command or Python function.  This also takes care of printing
+        a pre-substitution command for debugging purposes.
+
+    get_contents()
+        Fetches the "contents" of an Action for signature calculation
+        plus the varlist.  This is what gets MD5 checksummed to decide
+        if a target needs to be rebuilt because its action changed.
+
+    genstring()
+        Returns a string representation of the Action *without*
+        command substitution, but allows a CommandGeneratorAction to
+        generate the right action based on the specified target,
+        source and env.  This is used by the Signature subsystem
+        (through the Executor) to obtain an (imprecise) representation
+        of the Action operation for informative purposes.
+
+
+Subclasses also supply the following methods for internal use within
+this module:
+
+    __str__()
+        Returns a string approximation of the Action; no variable
+        substitution is performed.
+
+    execute()
+        The internal method that really, truly, actually handles the
+        execution of a command or Python function.  This is used so
+        that the __call__() methods can take care of displaying any
+        pre-substitution representations, and *then* execute an action
+        without worrying about the specific Actions involved.
+
+    get_presig()
+        Fetches the "contents" of a subclass for signature calculation.
+        The varlist is added to this to produce the Action's contents.
+
+    strfunction()
+        Returns a substituted string representation of the Action.
+        This is used by the _ActionAction.show() command to display the
+        command/function that will be executed to generate the target(s).
+
+There is a related independent ActionCaller class that looks like a
+regular Action, and which serves as a wrapper for arbitrary functions
+that we want to let the user specify the arguments to now, but actually
+execute later (when an out-of-date check determines that it's needed to
+be executed, for example).  Objects of this class are returned by an
+ActionFactory class that provides a __call__() method as a convenient
+way for wrapping up the functions.
