D. IMPLEMENTATION AND PRACTICALITIES
It is clearly possible
to design and produce such a package without reference to existing
packages. This could prove to be expensive and inappropriate, especially for a demonstration
package.
Given the number
of features common to other existing applications, there could be
considerable merit in adapting or "piggy-backing" on such initiatives.
There is also merit
in reflecting on the possibility of specifically designing the package as an
interface to other packages. In the simplest case it might be of immediate value as an interface
through which to order a complex set of word-processing documents that would normally be
held in a nested hierarchy of sub- directories.
