Q. What is "librock"?

A. Librock is software you can reuse immediately, without having to reinvent, without having to rework. Librock is a large collection of selected software from many different authors, standardized to be "easily and highly reusable" without rework.

Q. How is it different than other third-party libraries?

A. Because it is easier to reuse. Take a quick-look

Feature	The Benefit	How?
Friction-free acquisition	Source code that is Free (Libre) and free (no cost).	Distributed and updated via HTTP using automated tools, using LIDESC features to report and ensure license compatibility with local policy.
Collision-free naming	Expect no name collisions when you integrate with your project. The worst that could happen is that there is duplicated functionality which simply co-exists alongside your existing implementation.	Macros defined at compile time and names visible at link time are prefixed by "librock_".
Rock Stable API	Worry-free updates. Existing applications will not break when you update. Once set, the purpose, name, and arguments of a function in a newer version will not change.	Functions are fully tested to settle the APIs. In every future version, new functions will have new names, not replace existing functions.
Highly Portable	Works with many machines, compilers (including gcc and MSVC), and operating systems (including Windows, Linux, and BSD.)	All compiler, OS, and machine-specific features are selected in one place: the header file librock/target/local.h.
Well-documented	Description pages go beyond typical man pages. With the Rapid-Knowlege-Transfer subject index, easily locate manual pages even when you don't already know the name.	We create, adapt, and improve documentation and publish via HTTP. View cut-and-paste examples, multi-thread behavior, dependencies, licensing, links to source, and test results.

Q. I understand I get the software at no cost. What are the benefits received with a paid Librock subscription?

A. Subscriptions exist for using librock in professional-quality software development.

• Subscribers receive digitally signed and dated license certificates. Each digitally signed certificate include the name of the subscriber, SHS1 checksums of every source file, and the known original source and the license terms which apply to the subscriber. With these certificates comes a limited warranty that the named licenses apply to the subscriber. [More about this]

• Subscribers can verify source code integrity and tamper-proof distribution. The digitally signed license certificate and an automatic file integrity checker will verify that the software copies you have match our master sources exactly. This provides end-to-end verification of the fidelity of the distribution chain, plus a verification of your local repository. [More about this]

• Subscribers can customize the Librock download and update services. Everyone can download individual sources directly from the website. Only subscribers can select a subset of librock (based on attributes such as licensing, implementation language, or quality assurance), and then work with just that subset of librock: browsing documentation, downloading, and automatically updating their selected group of source files. Other items are removed from view, even from the topic-based index of documentation pages. [More about this].

• Subscribers can receive Change and Security Notices. Informational messages regarding changes, known defects, and security issues are not available to non-subscribers. The librock notification system supports archiving notices and transport over non-email media. (More at `Subscriber notification system`)

• Subscribers can receive test certificates which list the md5 checksums of source files in which all documented functions successfully passed regression tests. Quality assurance is serious business, and the test certification process is designed and automated so that human error does not slip anything onto the list untested. [More about this]

• Subscribers can leverage the LIDESC license awareness system. This is not an enforcement of license terms. (Everything in librock is Freely redistributable.) This is a way to report the exact copyright and license terms given a compiled binary or source. The system can be set up to report incompatibilities with local licensing policies and when licenses are combined. [More about this]
