+Try to detect a C compiler from the list of supported compilers (gcc, msvc, etc)::
+
+	def options(opt):
+		opt.load('compiler_c')
+	def configure(cnf):
+		cnf.load('compiler_c')
+	def build(bld):
+		bld.program(source='main.c', target='app')
+
+The compilers are associated to platforms in :py:attr:`waflib.Tools.compiler_c.c_compiler`. To register
+a new C compiler named *cfoo* (assuming the tool ``waflib/extras/cfoo.py`` exists), use::
+
+	from waflib.Tools.compiler_c import c_compiler
+	c_compiler['win32'] = ['cfoo', 'msvc', 'gcc']

+		opt.load('compiler_c')

+		cnf.load('compiler_c')
+	def build(bld):
+		bld.program(source='main.c', target='app')
+
+Not all compilers need to have a specific tool. For example, the clang compilers can be detected by the gcc tools when using::

+	$ CC=clang waf configure
