In one form, a method, for creating multiple segments of source information for
presentation on a device having a limited size display screen, includes generating
a first derivative file describing first presentation material. The derivative
file is derived from a first copy of a master style sheet file. The master style
sheet specifies a style of displaying the source information. The source information
includes a plurality of attributes, of which a first set of attributes are included
in the first derivative style sheet file. A second derivative file describing second
presentation material is derived from a second copy of the master style sheet file.
A second set of attributes included in the source information are included in the
second derivative file. The first presentation and second presentation materials
are generated responsive to the source information and the respective first and
second derivative files.
