Changes since V1(the previous versions was not enumerated):
*   fix the size of array cont_name - so no allocation and c_max variable
removed
*   change the sequence of processing of controllers list on input (now
first) and internal controller list(first in the previous version), now the
controllers are output in order in which they are put to input
*   fix return values/error messages - now if the controller is not mount
the tool return error - it returns 0 otherwise

Changes since V2
* fix the format of comments which have more than 1 line

* printf of help -> fprintf(stdout,
