VAInstall is a multi-platform installer written in Java. Through a simple config file, it allows the packager to pick files and directories from various places on disk, and not only one root dir like other installers. The packager can completely reorganize the files and dirs on the destination host. He can choose the install mode for the destination host (graphic, xtra, text, or ANSI). VAInstall takes minimum space on the destination host; it does not write any large temporary files on disk, and supports easy and powerful uninstallation.
