      Creates a snapshot of the current working directory and exports as an archive.

      .git, .gitignore, files listed in .drainpipeignore, and .drainpipeignore
      itself are not added. .drainpipeignore uses the same format as gitignore.

      If your .gitattributes file contains export-ignore or export-subst, these
      will be respected when exporting the archive.

        o=<file>   Write the archive to <file>. The compression format is
                   inferred from the file extension. Format options are:
