add

var Command = &command.Command{
	Usage: `add [-f|--file <range-file>] [--type <file-type>]
	<project-file> [<range-file>...]`,
	Short: "add taxon ranges to a PhyGeo project",
	Long: `
Command add reads one or more taxon ranges from one or more range files, and
add the ranges to a PhyGeo project. The ranges can be either presence-absence
pixelations, or a continuous range maps.

The first argument of the command is the name of the project file. If no
project exists, a new project will be created.

One or more range files can be given as arguments. If no file is given the
ranges will be read from the standard input. A pixelation model must be
already defined for the project, either a rotation model, or a paleolandscape
model, and the pixelation of the input files must be consistent with that
pixelation model.

By default, only the taxon with ranges defined as presence-absence will be
read. Use the flag --type to define the type of the ranges to be read. The
type can be:

	points	presence-absence taxon ranges
	ranges	continuous range map

By default the range maps will be stored in the range files currently defined
for the project. If the project does not have a range file, a new one will be
created with the name 'points.tab' for presence-absence taxon ranges, or
'ranges.tab' for continuous range maps. A different file name can be defined
with the flag --file or -f. If this flag is used, and there is a range file
already defined, then a new file will be created, and used as the range file
for the added type of range map for the project (previously defined ranges
will be kept).
