The Files and Folders Rules Evaluation Engine (FFREE, pronounced /ˈɛf-fri/) is a general-purpose rule processing engine and toolkit to create and evaluate XML-based rules on files and folders. The XML files generated by the toolkit and processed by the engine must strictly abide by version-specific XML Schema which can be found in the repository. FFREE makes extensive use of the C++17 filesystem library for file and directory traversal.
This package requires access to the Xerces-C library from the Apache Foundation.
On ubuntu, this can be fulfilled with sudo apt update && sudo apt install libxerces-c-dev.
