This tool lays somewhere between a Plate reconstruction demo and something that can be used to do real work. There are some dedicated software available on the web that do plate reconstructions but this one has a big advantage. It is ready to work upon start, and is very easy to use. There is no need to explain what the buttons do. They self explain with their tooltips. To access other fundamental options right-click over the "plates". New menus popup and is there that the user controls how the plates move. By default, the program associates a “movement history” to three plates: Iberia, Eurasia and Africa. The poles that show up in the window’s lower left corner define the movement. In addition to the default files, the user can load its own data. There are two types of data: the poles files, which control how the plates move; and the plate files. The poles used in this program are stage poles (not finite rotation poles). They have a particular format described in detail in the rotconverter GMT program, but the example files can be found at them at the "continents" directory of Mirone’s installation. To create new stage poles files from finite rotations poles hit the "Make stage poles" and follow instructions there. The plates files are simple ASCII files with two columns: longitude and latitude (in that exact order). Now, those files may be multi-segments, with the character ">" serving as the separator. The individual segments may be closed (equal first and last point). If they are closed, the contour is filled; otherwise they are drawn as lines. Very important: The first line in file must be of the form ''# Name'' (without the quotes), where Name is the plate’s name. This is the mechanism that the program uses to know how to associate a plate and its companion lines with a stage pole. We can see the default plates name when right-clicking over it, so if we want to add it another element (e.g. the 3000 m bathymetric) we must give in that file the exact same name as the plate we want it to join.
