Hi,
This is a Unix C question. But since I am doing something that ultimately

I am trying to build a third-party utility in Linux. I ran into troubles in

Use version_txt:
from App.version_txt import version_txt
version_string = version_txt()
In CVS versions of Zope this will return '(unreleased version)' though.
You could also test for the existence of registerHelp:
if hasattr(context, 'registerHelp'):
context.registerHelp()
Or your source files get white space after the "\" only when transported
to Linux; this may happen if under Linux the lines of your source files
still end with CR-LF (carriage return, line feed) as they do in Windows,
instead of only LF (the expected end of line character in Unix).
