+
+OVERVIEW
+
+icopen patches MacOS Python to use the Internet Config file mappings to select
+the type and creator for a file.
+
+Version 1 released to the public domain 3 November 1999
+by Oliver Steele (steele@cs.brandeis.edu).
+
+DETAILS
+
+This patch causes files created by Python's open(filename, 'w') command (and
+by functions and scripts that call it) to set the type and creator of the file
+to the type and creator associated with filename's extension (the
+portion of the filename after the last period), according to Internet Config.
+Thus, a script that creates a file foo.html will create one that opens in whatever
+browser you've set to handle *.html files, and so on.
+
+Python IDE uses its own algorithm to select the type and creator for saved
+editor windows, so this patch won't effect their types.
+
+As of System 8.6 at least, Internet Config is built into the system, and the
+file mappings are accessed from the Advanced pane of the Internet control
+panel.  User Mode (in the Edit menu) needs to be set to Advanced in order to
+access this pane.
+
+INSTALLATION
+
+Put this file in your Python path, and create a file named {Python}:sitecustomize.py
+that contains:
+	import icopen
+
+(If {Python}:sitecustomizer.py already exists, just add the 'import' line to it.)
+
+The next time you launch PythonInterpreter or Python IDE, the patch will take
+effect.
