Aladdin Systems is shipping its Mac OS X-friendly StuffIt Engine Software Developer Kit (SDK) 6.0.1 for the Mac.

SDK allows third-party software developers to put StuffIt technology into their own applications. It handles all popular compression and encoding formats, including AppleSingle, BtoA, Gzip, Unix Compress, Tar and Lha. Developers can also create or access StuffIt and Zip archives and add or remove encoding.

SDK creates and accesses the most common compression and encoding formats found on Windows, Linux, Unix and Macintosh.

SDK is available for download from Aladdin's Web site. License fees vary according to the type and scope of the project.
