Detailed Description

A virtual file system optimized for the dependency discovery.

It is primarily designed to work with source files whose contents was preprocessed to remove any tokens that are unlikely to affect the dependency computation.

This is not a thread safe VFS. A single instance is meant to be used only in one thread. Multiple instances are allowed to service multiple threads running in parallel.
