NAME
       regconcat - Combine several Regina data files

SYNOPSIS
       regconcat [ -o output-file ] input-file ...


       regconcat { -v, --version | -?, --help }


DESCRIPTION
       This utility combines several individual Regina data files into a
       single larger data file.  The new file will have a container as its
       top-level packet, and beneath this container will be the packet trees
       from each of the input files that you supply.

       If an output file is specified through option -o, the new file will be
       written as compressed XML to this output file.  Otherwise the new file
       will be written as uncompressed XML to standard output.

OPTIONS
       -o output-file
              Specifies that the new combined data file should be written as
              compressed XML to the given output file.

       -v, --version
              Show which version of Regina is being used, and exit
              immediately.

       -?, --help
              Display brief usage information, and exit immediately.
