> What is STREAMdiff? STREAMdiff is a high-speed print stream comparison tool that automates the document review/testing process by digitally comparing a file of "pre-change" and "post-change" documents and displaying them side-by-side on your PC screen. Color-coded markers of varying, user-designated shapes are used to highlight differences. Additionally, rules can be created to iteratively review and accept document differences.

> Which Page Description Languages (PDL's) can be compared using STREAMdiff? AFP (including AFP line data), PDF, Postscript, PCL (version 5), Metacode, and text/line data files can all be tested with STREAMdiff.  In fact, STREAMdiff can compare "like to like" files (e.g., compare one AFP file to another AFP file) or "like to unlike" files (e.g., compare a Metacode file to a Postscript file).

> Does STREAMdiff work in both interactive and batch modes?  Yes.  STREAMdiff can be launched on the desktop in an interactive mode or on a PC or server in a batch mode.  PowerSWITCH simplifies the use of STREAMdiff in a batch mode by eliminating the need for the user to manually start the batch process using a DOS command line interface.

> Can STREAMdiff compare files generated by different document creation/composition applications?  Yes.  STREAMdiff compares files on both a structural and visual basis.  This allows files from different versions of the same composition software, or even files generated by completely different document composition applications, to be accurately compared.

> On which operating systems does STREAMdiff run? Windows 2000, XP, or Vista

> What are the PC/server requirements for STREAMdiff?
