+// Package features allows probing for BPF features available to the calling process.
+//
+// In general, the error return values from feature probes in this package
+// all have the following semantics unless otherwise specified:
+//
+//	err == nil: The feature is available.
+//	errors.Is(err, ebpf.ErrNotSupported): The feature is not available.
+//	err != nil: Any errors encountered during probe execution, wrapped.
+//
+// Note that the latter case may include false negatives, and that resource
+// creation may succeed despite an error being returned. For example, some
+// map and program types cannot reliably be probed and will return an
+// inconclusive error.
+//
+// As a rule, only `nil` and `ebpf.ErrNotSupported` are conclusive.
+//
+// Probe results are cached by the library and persist throughout any changes
+// to the process' environment, like capability changes.
