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
size: length of input data; if missing, proper '\0'
termination is mandatory
