qmail-installer is a shell script that asks the user a few configuration questions, and then downloads, patches, installs, and configures qmail and its dependencies. Currently, the script installs daemontools and ucspi-tcp, and optionally qmailanalog, the SMTP AUTH patch, the qmail-queue patch, and the virus-scan-zip patch. The installer offers a number of modes (outbound only, outbound only with SMTP, normal, and normal with POP). The qmail installation performed by this script is compliant with Dan Bernstein's licensing, and is very close to an LWQ installation.
