[Zope-Checkins] CVS: Zope3/lib/python/Interface - pyskel.py:1.1.2.12

[Stephan Richter]

Update of /cvs-repository/Zope3/lib/python/Interface
In directory cvs.zope.org:/tmp/cvs-serv7757

Modified Files:
      Tag: Zope-3x-branch
	pyskel.py 
Log Message:
Okay, I have added something to pyskel.py that bugs me already since a long
time. Until now you could only use the Python dot syntax to specify an 
interface. That meant that I could not use my TAB key in the shell to 
wander through the directories. 

I therefore added some functionality that '/' are also allowed. Furthermore
you can use relative paths like ../Zope/I18n/IDomain.py if you are in the
Interface directory for example. I find that particularly helpful, since I
often reside in the directory of the package I am working in. So, if I am 
in Zope/I18n, I can say: 

pyskel.py ./IDomain.py

Note: Assuming pyskel in somewhere in your shell search path.
