Making a Python 2.7 package for OSGeo4W

Some rough notes for how I built a python 2.7 package.

Open a command shell and

set vv=27
set ver=2.7.2

:: install py27 from standard 32bit msi installer (outside o4w)
wget http://www.python.org/ftp/python/%ver%/python-%ver%.msi
start python-%ver%.msi

pushd d:\o4w-packages\python
mkdir python-%ver%
cd python-%ver%
mkdir apps bin etc

:: Add batch files for `etc\ini`, `etc\postinstall`, & `bin` from skeleton
xcopy /s ..\python-skeleton\* .\

Manually compare c:\python27 to previous o4w python installs, then reflect the structure

xcopy /s c:\python%vv% apps\Python%vv%
move apps\Python%vv%\*.exe bin\

if exist %windir%\SysWOW64\python%vv%.dll copy %windir%\SysWOW64\python%vv%.dll bin\
if exist %windir%\System32\python%vv%.dll copy %windir%\System32\python%vv%.dll bin\

Now create the package archive

:: append o4w package version
set ver=%ver%-1

7z a -ttar python-%ver%.tar apps bin etc
7z a -tbzip2 -mx9 -mmt=on python-%ver%.tar.bz2 python-%ver%.tar
