NAME
       gxl2dot,dot2gxl - GXL-DOT converters

SYNOPSIS
       gxl2dot [ -gd?  ] [ -ooutfile ] [ files ]
       dot2gxl [ -gd?  ] [ -ooutfile ] [ files ]

DESCRIPTION
       gxl2dot  converts between graphs represented in GXL and in the DOT lan-
       guage. Unless a conversion type is specified using a flag, gxl2dot will
       deduce  the  type  of  conversion  from the suffix of the input file, a
       ".dot" suffix causing a conversion from DOT to GXL, and a ".gxl" suffix
       causing  a conversion from GXL to DOT.  If no suffix is available, e.g.
       when the input is from a pipe, and  no  flags  are  used  then  gxl2dot
       assumes  the  type  of  the input file from its executable name so that
       gxl2dot converts from GXL to DOT, and dot2gxl converts from DOT to GXL.

       GXL  supports  a much richer graph model than DOT. gxl2dot will attempt
       to map GXL constructs into the analogous DOT  construct  when  this  is
       possible.  If  not,  the GXL information is stored as an attribute. The
       intention is that applying gxl2dot|dot2gxl is  semantically  equivalent
       to the identity operator.

OPTIONS
       The following options are supported:

       -g     The  command  name  and  input  file extensions are ignored, the
              input is taken as a DOT 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 DOT 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  DOT.   If
               no files operand is specified, the standard input will be used.

RETURN CODES
       Both gxl2dot and dot2gxl return 0 if there were no problems during con-
       version; and non-zero if any error occurred.

BUGS
       gxl2dot will only convert in one direction even if given multiple files
       with varying suffixes.

       The conversion can only handle one graph per GXL file.

GXL2DOT,DOT2GXL(1)                             GXL2DOT,DOT2GXL(1)


       There are some GXL constructs which gxl2dot cannot handle.
