## Supplemental archive in 3.3.1

The supplemental archive has undergone many significant changes:

dbase:
  Added optional final column to the grdraster.info database that can be set to L or B to indicate the endianness of the binary data file. A missing column means the data has the same endianness as the machine and no swapping is needed.

meca:
  The meca package comes with completely new tools for plotting symbols of importance to seismologiest and geodesists. The package now has two new tools (pscoupe and pspolar ), while the old psvelomeca has been separated into psmeca and psvelo .

mgg:
  The MGD77 reader mgd77togmt is now aware of the new Y2K-compliant MGD77 format and also will make a reasonable effort in handling older files.

spotter:
  New package with two tools for plate tectonic reconstructions: backtracker will move geological markers forward or backward in time, while hotspotter will apply the hotspotting technique to make a CVA image of potential hotspot locations. An announcement will shortly be published in EOS Trans. AGU.

x2sys:
  A new implementation of Wessel's crossover error estimation tool, which now is POSIX, ANSI-C, and Y2K complient, as well as faster. The package is generic and can extract data from arbitrary ASCII or binary data files with x2sys_datalist and calculate crossovers from the same files with x2sys_cross .
