(** [to_relative_path path] takes as input a file path [path], and constructs
an equivalent relative path from the current working directory. If [path]
is already relative, then it is returned immediately. *)

(** [normalize_path path] takes as input a file path [path], and returns an
equivalent path that: (1) does not contain the current directory member
["."] unless the path is to the current directory (in which case ["."]
is returned, or ["./"] if [path] has a trailing ["/"]), (2) only uses
parent directory members [".."] for a prefix of the path, and (3), has
a trailing ["/"] only if and only if [path] does.
For example, paths ["dir1/dir2/file.v"], ["."], ["dir1/dir2/dir3/"] and
["../../dir/file.v"] are possible return values, but ["./file.v"] and
["dir1/../dir2"] are not. *)
