/*
* Windows Installer program for distutils.
*
* (a kind of self-extracting zip-file)
*
* At runtime, the exefile has appended:
* - compressed setup-data in ini-format, containing the following sections:
* [metadata]
* author=Greg Ward
* author_email=gward@python.net
* description=Python Distribution Utilities
* licence=Python
* name=Distutils
* url=http://www.python.org/sigs/distutils-sig/
* version=0.9pre
*
* [Setup]
* info= text to be displayed in the edit-box
* title= to be displayed by this program
* target_version = if present, python version required
* pyc_compile = if 0, do not compile py to pyc
* pyo_compile = if 0, do not compile py to pyo
*
* - a struct meta_data_hdr, describing the above
* - a zip-file, containing the modules to be installed.
* for the format see http://www.pkware.com/appnote.html
*
* What does this program do?
* - the setup-data is uncompressed and written to a temporary file.
* - setup-data is queried with GetPrivateProfile... calls
* - [metadata] - info is displayed in the dialog box
* - The registry is searched for installations of python
* - The user can select the python version to use.
* - The python-installation directory (sys.prefix) is displayed
* - When the start-button is pressed, files from the zip-archive
* are extracted to the file system. All .py filenames are stored
* in a list.
*/
/*
* Includes now an uninstaller.
*/
/*
* To Do:
*
* display some explanation when no python version is found
* instead showing the user an empty listbox to select something from.
*
* Finish the code so that we can use other python installations
* additionaly to those found in the registry,
* and then #define USE_OTHER_PYTHON_VERSIONS
*
* - install a help-button, which will display something meaningful
* to the poor user.
* text to the user
* - should there be a possibility to display a README file
* before starting the installation (if one is present in the archive)
* - more comments about what the code does(?)
*
* - evolve this into a full blown installer (???)
