translate to the destination filesystem.
Software Elements
A software package is created from a hierarchy of software elements,
which are structured and defined in a PSF. The SPB-specific software
elements are as follows:
File A file is the lowest level of software element that can be
contained in a software package. Files are grouped
together to create filesets.
Fileset A fileset serves as a container for files, associated file
attributes, and separate control scripts. A fileset is
comprised of a group of files. Filesets are grouped and
contained in products. A fileset can only belong to one
product; however, a fileset may be referenced in
multiple subproducts within one product. A fileset can
also be included in multiple bundles through the
product it is contained within. A minimum of one
fileset is required for a PSF.
Product A product is a container for filesets, subproducts,
and/or control scripts specific to a software package.
Products are collections that form a set of related
software. A product can contain one fileset or multiple
filesets. Products can contain filesets specific to
different versions of the product and different
hardware platforms. All these different filesets can be
packaged together for distribution. A minimum of one
product is required for a PSF.
Subproduct A subproduct is a reference to groups of related filesets
within a product. For example, you might create a
subproduct that references a fileset grouping for the
entire runtime configuration, manuals, or
demonstration versions of the product. It is important
to remember that subproducts only reference filesets
and do not physically contain the fileset. The use of
subproducts is optional and considered an advanced
feature.
