Each package receives its own
space in the hierarchy. Each package is free to use a
flat space, or divide its space further into
sub-hierarchies. If multiple packages share a common
purpose they may use a shared toplevel hierarchy,
preferably with the same name as a shared (virtual)
package name (for example, both mutt and elm can use mail-reader , strn and nn could use news-reader ).
