var Command = &command.Command{
	Usage: `set [--tozero] [-i|--input <file>]
	<project>`,
	Short: "set ages of the nodes of a tree",
	Long: `
Command set reads the trees from a PhyGeo project and a list of node ages to
update the age of the indicated nodes.

The argument of the command is the name of the project.

The ages of the nodes are read from an input file defined with the --input or
-i flag. The ages file is a TSV file without a header with the following
columns:

    -tree  the name of the tree
    -node  the ID of the node to set
    -age   the age (in million years) of the node

The node ages must be consistent with any other age already defined on the
tree. The changes are made sequentially.


As an usual operation is to set ages of all terminals to 0 (present), the flag
--tozero is provided to automate this action. Note that the flag will set all
terminals in the project.
