This is the software publisher's description.

Self-Extracting Archive Utility (SEAU) builds a professional software installation program in a single compressed executable file. Offers full support for uninstallation, multiple languages, interface customization, license agreements, readme files, file associations, DOS batch operations, multiple disk spanning, DLL installation, automated installations, patches, expiration dates, shared files, command line archive building, and much more.

SEAU creates executable installation programs that are self-contained in a single file. A single file is easily downloaded, requires no software such as WinZip to decompress, and ensures that all installation files are present.

The installer's overhead is only 109 KB and the compression engine achieves a very high compression ratio. You will be amazed at how small SEAU can make the archive. SEAU can optionally provide support for uninstalling the product.

SEAU can create archives that span multiple disks. You can choose from several standard media sizes, or specify any arbitrary capacity. SEAU uses compression and every last byte of the media to ensure that the minimum number of disks are requested.
