"app" is the path to your Appy application, which must be a
|
|
Python package (= a folder containing a file named
|
|
__init__.py). Your app may reside anywhere, but needs to
|
|
be accessible by Zope. Typically, it may be or symlinked
|
|
in <yourZopeInstance>/lib/python, but not within the
|
|
generated product, stored or symlinked in
|
|
<yourZopeInstance>/Products.
|
|
|
|
"outputFolder" is the folder where the Zope product will be generated.
|
|
For example, if you develop your application in
|
|
/home/gdy/MyProject/MyProject, you typically specify
|
|
"/home/gdy/MyProject/zope" as outputFolder.
