+## pwalkdir: parallel implementation of filepath.WalkDir
+
+This is a wrapper for [filepath.WalkDir](https://pkg.go.dev/path/filepath#WalkDir)
+which may speed it up by calling multiple callback functions (WalkDirFunc)
+in parallel, utilizing goroutines.
+
+By default, it utilizes 2\*runtime.NumCPU() goroutines for callbacks.
+This can be changed by using WalkN function which has the additional
+parameter, specifying the number of goroutines (concurrency).
+
+### pwalk vs pwalkdir
+
+This package is very similar to
+[pwalk](https://pkg.go.dev/github.com/opencontainers/selinux/pkg/pwalkdir),
+but utilizes `filepath.WalkDir` (added to Go 1.16), which does not call stat(2)
+on every entry and is therefore faster (up to 3x, depending on usage scenario).
+
+Users who are OK with requiring Go 1.16+ should switch to this
+implementation.
+
+### Caveats
+
+Please note the following limitations of this code:
+
+* Unlike filepath.WalkDir, the order of calls is non-deterministic;
+
+* Only primitive error handling is supported:
+
+ * fs.SkipDir is not supported;
+
+ * no errors are ever passed to WalkDirFunc;
+
+ * once any error is returned from any walkDirFunc instance, no more calls
+ to WalkDirFunc are made, and the error is returned to the caller of WalkDir;
+
+ * if more than one WalkDirFunc instance will return an error, only one
+ of such errors will be propagated to and returned by WalkDir, others
+ will be silently discarded.
+
+### Documentation
+
+For the official documentation, see
+https://pkg.go.dev/github.com/opencontainers/selinux/pkg/pwalkdir
+
+### Benchmarks
+
+For a WalkDirFunc that consists solely of the return statement, this
+implementation is about 15% slower than the standard library's
+filepath.WalkDir.
+
+Otherwise (if a WalkDirFunc is actually doing something) this is usually
+faster, except when the WalkDirN(..., 1) is used. Run `go test -bench .`
+to see how different operations can benefit from it, as well as how the
+level of paralellism affects the speed.
