A package is the entity which WarpIN uses to manage installations. Packages are contained in archives (WPI files) and are stored in the global database after successful installation.

Note that packages are not files. Instead, a package is just a logical grouping of files. Each package must therefore be contained in an archive. In turn, each archive must contain at least one package.

Packages are also used by WarpIN to manage system configuration data.

Also, WarpIN is capable of managing package dependencies. This way WarpIN can warn you if you are installing packages which will not run without others, or if you are attempting to de-install a package which is still needed by others.
