BPython:

- based on a request by Campbell (he also provided a patch for scene.Layer) access to layers was improved a little, keeping the old method (ob.Layers is a bitmask) and adding the nicer one (ob.layers is a list of ints).  Done for objects and scenes.  House-cleaning: .Layer was renamed to .Layers (actually just using strncmp instead of strcmp, so both work, same done for Window.ViewLayers).
- finally committing patch by Ken Hughes to let .clearScriptLinks() accept a parameter (list of strings) to clear only specified texts.
- doc updates and fixes (JMS reported a problem in nmesh.transform() example code).

Thanks all who contributed.

  Configuring scripts:
  --------------------
 
- Configuration data is simple data used by your script (bools, ints, floats,
- strings) to define default behaviors.
+ The L{Blender.Registry<Registry>} module provides a simplified way to keep
+ scripts configuration options in memory and also saved in config files.
+ And with the "Scripts Config Editor" script in the System menu users can later 
+ view and edit the options easily.
 
- For example, an exporter might have:
-   - EXPORT_LIGHTS = False: a bool variable (True / False) to determine if it
-     should also export lights setup information;
-   - VERSION = 2.0: an int to define an specific version of the export format;
+ Let's first clarify what we mean by config options: they are simple data
+ (bools, ints, floats, strings) used by programs to conform to user
+ preferences.  The buttons in Blender's User Preferences window are a good
+ example.
+
+ For example, a particular exporter might include:
+   - SEPARATE_MATS = False: a bool variable (True / False) to determine if it
+     should write materials to a separate file;
+   - VERSION = 2: an int to define an specific version of the export format;
    - TEX_DIR = "/path/to/textures": a default texture dir to prepend to all
      exported texture filenames instead of their actual paths.
 
- To properly handle this, script writers had to keep this information in a
- separate config file (at L{Blender.Get}('udatadir') or, if not available,
- L{Blender.Get}('datadir')), provide a GUI to edit it and update the file
- whenever needed.
+ The script needs to provide users a GUI to configure these options -- or else
+ directly editing the source code would be the only way to change them.  And to
+ store changes made to the GUI so they can be reloaded any time the script is
+ executed, programmers have to write and load their own config files (ideally at
+ L{Blender.Get}('udatadir') or, if not available, L{Blender.Get}('datadir')).
 
- There are facilities in BPython now to take care of this in a simplified (and
- much recommended) way.
-
- The L{Registry} module functions L{GetKey<Registry.GetKey>} and
- L{SetKey<Registry.SetKey>} take care of both keeping the data in Blender
- and (new) storing it in config files at the proper dir.  And the 'Scripts
- Configuration Editor' script provides a GUI for users to view and edit
- configuration data.

 Registry
 ========
 
 This module provides a way to create, retrieve and edit B{persistent data} in
-Blender. When a script runs in Blender, it has its own private global
-dictionary, which is deleted when the script finishes. This is done to avoid
-problems with name clashes and garbage collecting.  But the result is that
-data created by a script isn't kept after it leaves, for itself or others to
-access later: the data isn't persistent. The Registry module was created to
-give script authors a way around this limitation.
+Blender.
 
-In Python terms, the Registry holds a dictionary of dictionaries.
-You should use it to save Python objects only, not BPython (Blender Python)
-objects -- but you can save BPython object names, since those are strings.
-Also, if you need to save a considerable amount of data, we recommend saving
-it to a file instead. There's no need to keep huge blocks of memory around when
-they can simply be read from a file.
+When a script is executed it has its own private global dictionary,
+which is deleted when the script exits. This is done to avoid problems with
+name clashes and garbage collecting.  But because of this, the data created by
+a script isn't kept after it leaves: the data is not persistent.  The Registry
+module was created to give programmers a way around this limitation.
 
-Examples of what this module can be used for:
-
-a) Saving data from a script that another script will need to access later.
-
-b) Saving configuration data for a script.  Users can view and edit this data
-using the "Scripts Configuration Editor" script, then.
-
-c) Saving configuration data from your script's gui (button values) so that the
-next time the user runs your script, the changes will still be there.  
+Possible uses:
+ - saving arbitrary data from a script that itself or another one will need
+   to access later.
+ - saving configuration data for a script: users can view and edit this data
+   using the "Scripts Configuration Editor" script.
+ - saving the current state of a script's GUI (its button values) to restore it
+   when the script is executed again.
 
 Example::
 
   import Blender
   from Blender import Registry
 
-  # first declare your global variables:
-  myvar1 = 0
-  myvar2 = 3.2
-  mystr = "hello"
-
-  # then check if they are already at the Registry (saved on a

+  amounts your script users should be clearly informed about it --
+  always keep in mind that you have no idea about their resources and the
+  applications they are running at a given time (unless you are the only
+  user), so let them decide.
+
+  There are restrictions to the data that gets automatically saved to disk by
+  L{SetKey}(keyname, dict, True):  this feature is only meant for simple data
+  (bools, ints, floats, strings and dictionaries or sequences of these types).
+  Strings are clamped if longer than 300 characters and at most 60 elements are
+  allowed.  Since this is only meant for scripts configuration variables,
+  these are sensible restrictions, generous enough for the task.
+
+  For more demanding needs, it's of course trivial to save data to another 
+  file or to a L{Blender Text<Text>}.
