       This script will detect existing swap partitions or swap files, and encrypt them, using cryptsetup.

       Encrypted  swap  is  essential  to securing any system using eCryptfs, since decrypted file contents will
       exist in the system's memory, which may be swapped to disk at any time.  If the system swap space is  not
       also encrypted, it is possible that decrypted files could be written to disk in clear text.

       Note  that  most  Linux  distributions do not yet support resuming from an encrypted swap space, and thus
       hibernate/resume will not work.  Suspend/resume is unaffected.

       Upon running the utility, the user will be informed of the hibernate/resume break, and asked  to  confirm
       the behavior.  The -f|--force option can be used to bypass this interactive prompt.
