|

;;; Commentary:
|
||
|
||
;; This is a Q&D hack for conversion of Python manuals to on-line help format.
|
||
;; I desperately needed usable online documenta for Python, so I wrote this.
|
||
;; The result code is ugly and need not contain complete information from
|
||
;; Python manuals. I apologize for my ignorance, especially ignorance to
|
||
;; python.sty. Improvements of this convertor are welcomed.
|
||
|
||
;; How to use it:
|
||
;; Load this file and apply `M-x py2texi'. You will be asked for name of a
|
||
;; file to be converted.
|
||
|
||
;; Where to find it:
|
||
;; New versions of this code might be found at
|
||
;; http://www.zamazal.org/software/python/py2texi/ .
