GXL2GV,GV2GXL(1)								 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 language. Unless a conver-
       sion 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 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.

       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.

OPTIONS
       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.

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 conversion; and  non-zero
       if any error occurred.

BUGS
       gxl2gv  will  only convert in one direction even if given multiple files with varying suf-
       fixes.

       The conversion can only handle one graph per GXL file.

       There are some GXL constructs which gxl2gv cannot handle.
