AOL Web Server 4 (Program)
This is the web engine that powers the mighty America On-Line. It is capable of serving a tremendous number of users, and can publish hundreds of virtual servers within the same process at the same time. It is similar in many respects to Zope, except based largely on Tcl. It is multi-threaded, and has a C API that can be used to extend its functionality.
More information about apt-get remove
Advanced Package Tool, or APT, is a free software user interface that works with core libraries to handle the installation and removal of software on Debian, Ubuntu and other Linux distributions. APT simplifies the process of managing software on Unix-like computer systems by automating the retrieval, configuration and installation of software packages, either from precompiled files or by compiling source code.
apt-get is the command-line tool for handling packages, and may be considered the user's "back-end" to other tools using the APT library.
apt-get remove is identical to install except that packages are removed instead of installed. Note that removing a package leaves its configuration files on the system. If a plus sign is appended to the package name (with no intervening space), the identified package will be installed instead of removed.
