deploySICS.sh copies SICS and the files listed
in the MANIFEST.TXT files to the IC host.
Usage:
  ./deploySICS.sh [-n] INSTRUMENT [TARGET_HOST [TARGET_DIR]]
where
  -n if present inhibits the actual deployment (for testing the script)
  INSTRUMENT can be hrpd, echidna, hipd, wombat, ...
    or test/INSTRUMENT or INSTRUMENT/test for test deployment
  TARGET_HOST can be a remote host or 'localhost'
    defaults to ics1-<instrument>.nbi... or ics1-test.nbi... for test
  TARGET_DIR is the top part of the directory tree
    defaults to /usr/local or /usr/local/TEST_SICS/<instrument> for test
tail directories in TARGET_DIR will be created on TARGET_HOST if necessary.
Examples:
  ./deploySICS.sh -n echidna
    prepares deployment of echidna (./hrpd)
    to directory /usr/local/sics on isc1-echidna.nbi.ansto.gov.au
  ./deploySICS.sh -n reflectometer/test
    prepares deployment of platypus (./reflectometer)
    to directory usr/local/TEST_SICS/platypus on isc1-test.nbi.ansto.gov.au
  ./deploySICS.sh -n test/echidna localhost $HOME
    prepares deployment of echidna (./hrpd)
    to directory $HOME/TEST_SICS/echidna on localhost
