InfoSetter is an Adobe Acrobat plug-in that enables you to set document information pertaining to your PDF document(s). This tool allows you to set or change the standard PDF's document information fields listed below: Title, Subject, Author, Keyword, Index, Base URL. Why not just use Acrobat? It is possible to set this information in Acrobat, but InfoSetter allows you to store this data away in a configuration set and existing document properties can be quickly extracted from another PDF file that can not be done in Acrobat. The configuration name can then be quickly selected and applied to another PDF file.
