XTide is a package that provides tide and current predictions in a wide variety of formats. Graphs, text listings, and calendars can be generated, or a tide clock can be provided on your desktop. . This package provides the harmonics data used by the xtide package to display tidal information for most parts of the world. The data are packaged separately from xtide because they may be updated separately. . Some data omitted from the upstream harmonics file because of restrictions on commercial distribution and were included in the non-free package xtide-data-nonfree.
