Zope Static Call Tree is a Zope2 Product which scans the folder structure of a Zope2 installation and records relationships between Page Templates, Python Scripts and ZSQL methods.
The Basic idea is to find out what calls what, and what is called by what. It simply creates an instance of the package in a folder, scans the folder, and it will extract calls from PythonScripts, and ZPTs. The packages includes three trivial parsers. It is easy to add your own. This package was inspired by ZopeSecurityAudit.
