[Zope] Log in Plain Text

[Juan Manuel Ruiz García]

Hi,

I'm interested in tracing actions of my code to a plain txt file in each
folder of the application. I just want to add one or more lines to the log
after some actions take place, and I want to know if there's a simple method
to write one line to that log.txt

I think I can use "manage_editFile",  but it implies reading all the content
and adding the new line, but I'm not interested in reading it, just add the
line!! I think it would be a useless-complex-method reading it before

Help, please. Thanks in advance
