libdieharder2 package information
Random-number generator test library
libdieharder is the core library of dieharder and friends, designed to be "the last suite of random number testers you'll ever wear". It can test any of its many prebuilt and library linked generators (basically all of those in the GNU Scientific Library plus a number of others from various sources) or a potentially random dataset in either an ascii-formatted or raw (presumed 32 bit uint) binary file. It is fairly straightforward to wrap new software generators for testing, or to add hardware generators that have a software interface for testing, and the file input method permits pretty much any software or hardware RNG to be tested using libdieharder calls. libdieharder has as a design goal the full encapsulation in an extensible shell of basically all the random number tests I have been able to find -- George Marsaglia's "diehard" battery of tests, STS (v1.6) from NIST FIPS, Knuth's tests, and more. Check in the man page(s) or /usr/share/dieharder*/dieharder.pdf for documentation. This package provides the shared library.
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.
