regconcat — Combine several Regina data files


regconcat [-o output-file] {input-file...}


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.


-o output-file

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