Autoslack is designed to keep your Slackware Linux system up to date automatically. It reads a configuration file to get the FTP site you wish to use, the distribution directory to use, and where to store the packages on your system. It will show what's been updated based on what you have installed, what's new since you installed, and optionally download and install the packages.
RFC 2015 defines a proposed Internet standard for sending PGP-encrypted email. This PGP/MIME has been incorporated into several MUAs such as Mutt and (with the AEGYPTEN project) KMail. However, a lot of email clients still don't support it. pgp-mime-handler can decrypt/verify such messages via a pipe, so it can be used as an email filter in many programs or scripts.
glogin is a program that can be used to cause a terminal (usually a virtual console) to be logged in automatically, without having to type a userid and password. Stick it in place of getty in /etc/inittab to have terminals come up logged in and at a shell prompt at every boot. Same purpose as 'alogin', but you use it a little differently, and it does a little more of the usual login stuff. It is a simple Perl program, and can be easily customized.
va (virtual administration) is a console based script for the administration of virtual Web, mail, and DNS servers for multiple domains hosted on one or two Linux machines. It configures the standard (suse) Linux servers, and allows you to make changes to the configuration files. It will configure the following servers: Web server, apache with virtual hosts (create and remove domains) ftp server, set up ftp upload accounts mail server, and bind (set up primary and secondary name servers).
