1//! The set of origin paths for each read input argument.
2//!
3//! An origin path is the associated directory for which each parsed command
4//! line argument is relative to. So, for example, arguments read in from files
5//! are relative to the directory the file lives within, whereas arguments
6//! provided on the command line are relative to the current working directory.
7//!
8//! This mechanism ensures that, when files or directories are specified as
9//! inputs, we know the prefix to join to those paths to resolve the final
10//! location of each path.
