A harmonic tide clock and tide predictor The Tide and XTide programs generate and display tidal information for any geographic location which has an appropriate set of harmonic constants. By default, it is a simple tide clock, but it has command line switches to generate graphs, listings, calendars, and all kinds of good stuff. Tide and XTide are the work of David Flater, with the help of numerous contributors: Jef Poskanzer; Jack Greenbaum; Rob Miracle; Geoff Kuenning; Dale DePriest; Stan Uno; Dean Pentcheff; Jeff Dairiki; and Eric Rosen. It can be distributed or modified under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version. This RPM binary distribution of tide and xtide includes the harmonic constants database distributed from the xtide home page, (see below). If you want to use a system wide configuration file, this distribution was configured at compile time to use the names "/etc/tiderc", and "/etc/xtiderc" for Tide and XTide respectively. For more information, see the xtide man page, or the README file in the sub-directory in /usr/doc associated with xtide.
This program gives you all the features you need to create basic- to intermediate-level vector graphics, including bezier curves, lines, rulers, and m (Not Specified)
