      3 OVERVIEW
      4 
      5 icopen patches MacOS Python to use the Internet Config file mappings to select
      6 the type and creator for a file.
      7 
      8 Version 1 released to the public domain 3 November 1999
      9 by Oliver Steele (steele (at] cs.brandeis.edu).
     10 
     11 DETAILS
     12 
     13 This patch causes files created by Python's open(filename, 'w') command (and
     14 by functions and scripts that call it) to set the type and creator of the file
     15 to the type and creator associated with filename's extension (the
     16 portion of the filename after the last period), according to Internet Config.
     17 Thus, a script that creates a file foo.html will create one that opens in whatever
     18 browser you've set to handle *.html files, and so on.
     19 
     20 Python IDE uses its own algorithm to select the type and creator for saved
     21 editor windows, so this patch won't effect their types.
     22 
     23 As of System 8.6 at least, Internet Config is built into the system, and the
     24 file mappings are accessed from the Advanced pane of the Internet control
     25 panel.  User Mode (in the Edit menu) needs to be set to Advanced in order to
     26 access this pane.
     27 
     28 INSTALLATION
     29 
     30 Put this file in your Python path, and create a file named {Python}:sitecustomize.py
     31 that contains:
     32         import icopen
     33 
     34 (If {Python}:sitecustomizer.py already exists, just add the 'import' line to it.)
     35 
     36 The next time you launch PythonInterpreter or Python IDE, the patch will take
     37 effect.
