    Debugging command.

    The first two keywords LUN and IMAGE print the status of reserved  Logi-
    cal UNit numbers (LUN), or of allocated image slots (IMAGE).

    The  MEMALIGN  keyword  will  check if dynamically allocated buffers are
    aligned on 4, 8, 16 and 32 bytes. Some  applications  (e.g.  FFTW3)  are
    more or less faster dependending on the buffer alignment in memory.

    The  MESSAGE  keyword  swaps  ON or OFF the debugging mode for messages.
    When turning it ON, all messages to both screen and  message  files  are
    enabled. In this case it is a shortcut of the commands:
       SIC MESSAGE GLOBAL ON
       SIC MESSAGE GLOBAL A=FEWRIDTCU
    When turning it OFF, standard message filters (maybe customized by user)
    are re-enabled. It is a shortcut of the command:
       SIC MESSAGE GLOBAL OFF
    Default is debug mode turned OFF, unless a '-d' option has been provided
    when invoking the Gildas executable.

    The GFORTRAN keyword will check if the program is able to read and write
    correctly Gildas binary files. Some versions of  the  Gfortran  compiler
    have  an  issue  on this point, this command is intended to give a clear
    status to the user.

    The RESOURCES keyword will display current  resource  usage  and  limits
    (memory,  files, etc). See man pages for getrusage and getrlimit for de-
    tails (Linux only).

    The PYTHON keyword will display the Python version  which  was  used  to
    compile  Gildas against the one used at run time. If they are different,
    this probably means troubles.

    The VARIABLES keyword will display a technical list of the variables de-
    fined in Sic.
