 | Module | Description |
 | ------ | ----------- |
+| [Check](https://libcheck.github.io/check/) | Check is a unit testing framework for C. It features a simple interface for defining unit tests, putting little in the way of the developer. Tests are run in a separate address space, so both assertion failures and code errors that cause segmentation faults or other signals can be caught. Test results are reportable in the following: Subunit, TAP, XML, and a generic logging format. |

 | [libreadline](https://tiswww.case.edu/php/chet/readline/rltop.html) | The GNU Readline library provides a set of functions for use by applications that allow users to edit command lines as they are typed in. Both Emacs and vi editing modes are available. The Readline library includes additional functions to maintain a list of previously-entered command lines, to recall and perhaps reedit those lines, and perform csh-like history expansion on previous commands. |
 | [libtool](http://www.gnu.org/software/libtool) | GNU libtool is a generic library support script. Libtool hides the complexity of using shared libraries behind a consistent, portable interface. |
 | [libunwind](http://www.nongnu.org/libunwind/) | The primary goal of libunwind is to define a portable and efficient C programming interface (API) to determine the call-chain of a program. The API additionally provides the means to manipulate the preserved (callee-saved) state of each call-frame and to resume execution at any point in the call-chain (non-local goto). The API supports both local (same-process) and remote (across-process) operation. As such, the API is useful in a number of applications |
