       gxl2gv,gv2gxl - GXL-GV converters


       gxl2gv [ -gd?  ] [ -ooutfile ] [ files ]
       gv2gxl [ -gd?  ] [ -ooutfile ] [ files ]


       gxl2gv  converts  between  graphs  represented  in  GXL  and  in the GV
       language. Unless a conversion type is specified using  a  flag,  gxl2gv
       will deduce the type of conversion from the suffix of the input file, a
       ".gv" (or a ".dot") suffix causing a conversion from GV to GXL,  and  a
       ".gxl"  suffix  causing  a  conversion from GXL to GV.  If no suffix is
       available, e.g. when the input is from a pipe, and no  flags  are  used
       then gxl2gv assumes the type of the input file from its executable name
       so that gxl2gv converts from GXL to GV, and gv2gxl converts from GV  to

       GXL  supports a much richer graph model than GV. gxl2gv will attempt to
       map GXL constructs  into  the  analogous  GV  construct  when  this  is
       possible.  If  not,  the GXL information is stored as an attribute. The
       intention is that applying gxl2gv|gv2gxl is semantically equivalent  to
       the identity operator.


       The following options are supported:

       -g     The  command  name  and  input  file extensions are ignored, the
              input is taken as a GV file and a GXL file is generated.

       -d     The command name and input  file  extensions  are  ignored,  the
              input is taken as a GXL file and a GV file is generated.

       -?     Prints usage information and exits.

       -o outfile
              If  specified, the output will be written into the file outfile.
              Otherwise, output is written to standard out.


       The following operand is supported:

       files   Names of files containing 1 or more graphs in GXL or GV.  If no
               files operand is specified, the standard input will be used.


       Both  gxl2gv  and  gv2gxl  return  0  if  there were no problems during
       conversion; and non-zero if any error occurred.


       gxl2gv will only convert in one direction even if given multiple  files
       with varying suffixes.

       The conversion can only handle one graph per GXL file.

       There are some GXL constructs which gxl2gv cannot handle.
