<div class="PlainText">The working directory entry does what it says. The debugger process does a
<br>
kind of 'cd' into this directory and is started thereafter.<br>
<br>
Another possibility should be to set the PYTHONPATH environment variable. This <br>
could be set in the named dialog as well as permanently in the project <br>
debugger properties (Project menu -> Debugger submenu).<br>
<br>
I am open for suggestions for what stuff should be part of a virtual <br>
environment definition and how it should be used.<br>
