+Build Systems
+=============

+These are tools to automate the building and testing of projects in C.

+* [aimake][97] - A build tool designed to avoid complex configurations. [GNU GPL3][41].
+* [Autoconf][305] - An extensible package of M4 macros that produce shell scripts to automatically configure software source code packages. Part of the Autotools. [GNU GPL3][41].
+* [Automake][306] - A tool for automatically generating ``Makefile.in`` files compliant with the GNU Coding Standards. Requires the use of Autoconf. Part of the Autotools. [GNU GPL3][41].
+* [Jam][334] - A build system, designed to be easier than make. Understands C build rules implicitly. [Jam License][335].
+* [Libtool][172] - A generic library support script. [GNU GPL3][41].
+* [Meson][368] - An extremely fast, user-friendly build system. Based on Ninja. [Apache2.0][32].
