GXL2GV,GV2GXL(1)            General Commands Manual           GXL2GV,GV2GXL(1)

NAME
       gxl2gv,gv2gxl - GXL-GV converters

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

DESCRIPTION
       gxl2gv  converts  between  graphs represented in GXL and in the GV lan-
       guage. 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" 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  as-
       sumes  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.

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

OPTIONS
       The following options are supported:

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

       -d     The  command name and input file extensions are ignored, the in-
              put 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.

OPERANDS
       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.

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

BUGS
       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.
