+# SYNOPSIS
+#
+#   AX_CHECK_LIBRARY(VARIABLE-PREFIX, HEADER-FILE, LIBRARY-FILE,
+#                    [ACTION-IF-FOUND], [ACTION-IF-NOT_FOUND])
+#
+# DESCRIPTION
+#
+#   Provides a generic test for a given library, similar in concept to the
+#   PKG_CHECK_MODULES macro used by pkg-config.
+#
+#   Most simplest libraries can be checked against simply through the
+#   presence of a header file and a library to link to. This macro allows to
+#   wrap around the test so that it doesn't have to be recreated each time.
+#
+#   Rather than define --with-$LIBRARY arguments, it uses variables in the
+#   same way that PKG_CHECK_MODULES does. It doesn't, though, use the same
+#   names, since you shouldn't provide a value for LIBS or CFLAGS but rather
+#   for LDFLAGS and CPPFLAGS, to tell the linker and compiler where to find
+#   libraries and headers respectively.
+#
+#   If the library is find, HAVE_PREFIX is defined, and in all cases
+#   PREFIX_LDFLAGS and PREFIX_CPPFLAGS are substituted.
+#
+#   Example:
+#
+#     AX_CHECK_LIBRARY([LIBEVENT], [event.h], [event], [],
+#                      [AC_MSG_ERROR([Unable to find libevent])])
