HOW TO create a minimal numpy ?  (for fast import or freezing) 
==============================================================
rk 2009-05-16


* Make a copy of the original numpy folder tree
* ( Rename the original tree / remove from sys.path )
* Keep only those files/folders:

numpy/
-rw-rw-rw-   1 user     group          82 May 16 10:58 __init__.py
-rw-rw-rw-   1 user     group         593 Apr 28 21:16 version.py

numpy/core/
-rw-rw-rw-   1 user     group         961 May 16 11:15 __init__.py
-rw-rw-rw-   1 user     group        8938 Apr 28 21:16 _internal.py
-rw-rw-rw-   1 user     group       16814 May 16 11:31 arrayprint.py
-rw-rw-rw-   1 user     group       61754 Apr 28 21:16 fromnumeric.py (optional)
-rw-rw-rw-   1 user     group        4635 Apr 28 21:16 info.py
-rw-rw-rw-   1 user     group      505132 Apr 28 21:16 multiarray.pyd  (.so)
-rw-rw-rw-   1 user     group       56471 May 12 22:12 numeric.py
-rw-rw-rw-   1 user     group       20774 May 11 23:48 numerictypes.py
-rw-rw-rw-   1 user     group      318670 Apr 28 21:16 umath.pyd  (.so)

(about 300kB compressed on win32)

* change numpy/__init__.py to simply:

========== numpy/__init__.py ========================================
""" a minimal numpy - only essential stuff of the core """ #$1
import core
from core import *
========== end of numpy/__init__.py =================================


* run the patch below in numpy/core/

* (the strip-off regarding 'fromnumeric' is optional)

* from there re-add just the stuff you need 


========== patch in numpy/core/ =======================================
