       Zimpl  is a little language to translate the mathematical model of a problem into a linear
       or (mixed-)integer mathematical program expressed in LPF or MPS file format which  can  be
       read by a LP or MIP solver.

       None  of  the  options  is  necessary.  All  input  files in zpl format that are given are
       concatenated and processed as if they are one big file. This makes is possible to  combine
       different parts of a model on the command line. In this case the first filename given will
       be used as basename for the output files in absence of an -o option.

       The -t option is to select the output format.  mps can be read by every solver.  lpf is an
       CPLEX  format, but can also read by several solvers.  BE aware that for example Range-rows
       can not be expressed in lpf .  If you want to inspected the output yourself, hum format is
       a  variant of lpf with no name mangeling whatever, but unfortunately this violates several
       format restrictions, so no solver will read this in.  If rlp is specified the output is in
       lpf format, but rows and columns are randomly permuted.


       -b     Enable bison(1) debugging output.

       -D name=value
              Sets the parameter name to the specified value. This is equivalent with having this
              line in the Zimpl program: param name:=val .

       -f     Enable flex(1) debugging output.

       -F filter
              The output is piped through a filter. A %s in the string is replaced by the  output
              filename. For example: -F "gzip -c >%s.gz" would compress all the output files.

       -h     Show program help.

       -l length
              Sets the maximum length for variable names in LPF output files.

       -m     Write a CPLEX .mst Mip STart file.

       -n cm|cn|cf
              Select  the  format  for the generation of constraint names. Can be either cm which
              will number them 1 ... n with a `c' in front.  cn will use the name supplied in the
              subto statement and number them 1 ... n within the statement.  cf will use the name
              given with the subto, then a 1 .. n number like in cm and then append all the local
              variables from the forall statements.

       -o outfile
              Sets  the  base-name  for  the  output files. Default is the name of the input file
              without extension.

       -O     Optimize the generated LP by doing some presolve analysis (experimental).

       -P filter
              The input is piped through a filter. A %s in the string is replaced  by  the  input
              filename.  For example: -F "cpp -DWITH_C1 %s" would pass the input file through the

       -r     Write a CPLEX .ord branching order file.

       -s seed
              Set the random number generator seed.

       -t lp|mps|hum|rlp|pip
              Selects the output format. Can be either lp which is default, or mps  ,  or  hum  ,
              which is (only) human readable, or rlp , which is randomly permuted, or pip , which
              means polynimial IP.

       -v 0-5 Set the verbosity level. 0 is quiet, 1 is default, 2 is verbose, 3 is chatter,  and
              5 is debug.

       -V     Prints the version number.


       The following diagnostics may be issued on stderr:

       101 Bad filename
              The  name  given  with the -o option is either missing, a directory name, or starts
              with a dot.
       175 Illegal syntax for command line define -- ignored
              The parameter of a -D option was either not of the form name=value or the name  was
              not a legal identifier.
       There  are  about  a hundred other possible error messages, but these are either about the
       contend of the input file, or system messages.
