+ * strives to be SUSv3 compliant in it's behaviour when recursively
+ * making missing parent dirs, and in it's mode setting of the final
+ * directory 'path'.
+ *
+ * To recursively build all missing intermediate directories, make
+ * sure that (flags & FILEUTILS_RECUR) is non-zero. Newly created
+ * intermediate directories will have at least u+wx perms.
+ *
+ * To set specific permissions on 'path', pass the appropriate 'mode'
+ * val. Otherwise, pass -1 to get default permissions.
