NAME

       rst_deck - Convert simulation deck to a deck ready for restart

DESCRIPTION

       The rst_deck program will load a simulation deck and parameters for a restart and reformat
       the deck to become a restart deck. Before the updated deck  is  output  the  program  will
       update  the SOLUTION and SCHEDULE sections. All keywords from the SOLUTION section will be
       cleared out(1) and a RESTART keyword will be inserted. In the SCHEDULE section the program
       can either remove all keywords up until the restart date, or alternatively insert SKIPREST
       immediately following the SCHEDULE keyword.

       When creating the updated restart deck the program can either link to  unmodified  include
       files  with INCLUDE statements, create a copy of deck structure in an alternative location
       or create one large file with all keywords in the same file. Apart from the alterations to
       support  restart  the  output deck will be equivalent to the input deck, but formatting is
       not retained and comments have been stripped away.

       Arguments:

       1. The data file we are starting with.

       2. The restart source; this can either be a basename with an optional path

              prefix and a :N to restart from step N; alternatively you can point to an  existing
              restart  file. If you point to an existing restart file the input will be validated
              in several ways:

              a) Unified/multiple files will be checked against the UNIFIN setting of

              the deck.

              b) Formatted/unformatted will be checked against the FMTIn setting of the

              deck.

              c) If a single file like /path/to/case/HISTORY.X0067 is given as argument the

              :N notation to denote report step should not be used.

              If the restart argument is given as the path to an existing file the content of the
              RESTART  keyword  will  be updated to contain the correct path from the location of
              the restart deck to the location of the restart file. This path awareness  will  be
              fooled  if the restart deck is redirected from stdout to a path different from cwd.
              If the restart argument is given as an absolute filename the RESTART  keyword  will
              have  an  absolute  path,  if  the  restart argument is a relative path the RESTART
              keyword will get a relative path - although an absolute path will be  used  if  the
              restart  file  and the output deck have different roots. If the restart argument is
              given as a string not pointing to an existing file it will be inserted verbatim  in
              the restart deck.

              A  restart  step value of 0 is interpreted as a dry run - a deck which has not been
              set up for restart will be written out.

       3. Basename of the restart deck we create, can optionally contain a path prefix;

              the path will be created if it does not already exist. This argument  is  optional,
              if  it  is  not  provided  the  program  will dump a restart deck on stdout. If the
              argument corresponds to an existing directory the restart case will  get  the  same
              name as the base case.

OPTIONS

       -s: Manipulate the SCHEDULE section by inserting a SKIPREST keyword immediately

              following  the  SCHEDULE keyword. If the -s option is not used the SCHEDULE section
              will be modified by removing all keywords until we reach the restart date.

       -m: [share|inline|copy] The restart deck can reuse the unmodified include files

              from the base case, this is mode 'share' and is the default. With mode 'inline' the
              restart  deck  will be one long file and with mode 'copy' the file structure of the
              base case will be retained. The default if no -m option is  given  is  the  'share'
              mode.

              In  the  case  of  'share'  and  'copy'  the  correct path to include files will be
              negotiated based on the path given to the output case in the  third  argument.   If
              the  restart  deck  is passed to stdout the include files will be resolved based on
              output in cwd.

       Example:

              rst_deck /path/to/history/HISTORY.DATA rst/HISTORY:30 /path/to/rst/RESTART -s

       1: The program has a compiled list of keywords which will be retained in the

              SOLUTION section. The current value of that list is: RPTRST
