* -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
