StuffIt(tm), today announced it is now shipping the StuffIt Engine(tm)
Software Developer'S Kit (SDK), version 6.5.1 for Macintosh. The

developers are turning to Aladdin's one-stop solution to use with all
their products," said David Polzine, developer relations product

any software application, developers can access and create StuffIt or
Zip archives, add or remove encoding, or make self-extracting archives
for Mac or Windows desktop users. The StuffIt Engine SDK for Macintosh

StuffIt (including encrypted and/or segmented), Zip, Self-Extracting
Archive for Macintosh, Self-Extracting Archive for Windows, Apple
