No.  Although peak.running.tools.version actually has some code that writes 
an .ini file.  But the .ini file in question isn't intended for use by humans.

If you need to edit a config file, it would probably be best to follow the 
example of the 'version' tool, as it edits the file in such a way that the 
original file isn't overwritten until/unless the new copy is successfully 
written.  And, it uses the peak.storage transaction API, so you can have 
the config file update be part of a larger transaction.

I imagine that you could in fact write code to edit an .ini file in more 
sophisticated ways than that code does.  I just haven't had a need for it yet.

Only by re-creating the components involved.  Presumably, one could create 
a config file loader subclass that would look for specific values and 
re-interpret them, but I have not had a need for such a thing as yet.
