+ umask mask
+
+This function sets the mask used for creating new files and
+device nodes to C<mask & 0777>.
+
+Typical umask values would be C<022> which creates new files
+with permissions like "-rw-r--r--" or "-rwxr-xr-x", and
+C<002> which creates new files with permissions like
+"-rw-rw-r--" or "-rwxrwxr-x".
