- * 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 (???)
