Detailed Description

Contains two functions to compute expanded form of a given path.

Given a path in the file system, compute an expanded form. An expanded path is one which does not

• involve any symbolic links
• involve any . or ..
• begin with a ~
• contain any trailing or repeated /

The result of each query is cached so that a subsequent query on the same path will be much faster and will not involve any system calls.
