//! Filesystem helpers for the package system.
//!
//! `copy_dir_recursive` is used during install to materialise a package
//! into the packages dir. `find_single_subdir` handles the common case
//! of an extracted archive that nests the package under a single
//! root directory. `prune_empty_parents` keeps the git/npm scoped
//! install dirs tidy after removal.
