- * env import [-d] [-t | -b | -c] addr [size]
+ * env import [-d] [-t [-r] | -b | -c] addr [size]
  *     -d:     delete existing environment before importing;
  *             otherwise overwrite / append to existion definitions
  *     -t:     assume text format; either "size" must be given or the
  *             text data must be '\0' terminated
+ *     -r:     handle CRLF like LF, that means exported variables with
+ *             a content which ends with \r won't get imported. Used
+ *             to import text files created with editors which are using CRLF
+ *             for line endings. Only effective in addition to -t.
  *     -b:     assume binary format ('\0' separated, "\0\0" terminated)
  *     -c:     assume checksum protected environment format
  *     addr:   memory address to read from
