Uninstall IGS 6.40 : UNIX?????

Hi,

During our initial install of IGS 6.40 on UNIX, we filled up a file system. We've since added plenty of space, and would like to reinstall the IGS, but I can't find any information on uninstalling the IGS for UNIX. There is plenty of documentation for Windows, but a UNIX uninstall seems to be missing. Can anyone tell me where I can find this documentation, or if the uninstall for UNIX is simply a matter of deleting all pertinent directories? Thanks for your help.
