+dnl @synopsis AC_PATH_GENERIC(LIBRARY [, MINIMUM-VERSION [, ACTION-IF-FOUND [, ACTION-IF-NOT-FOUND]]])
+dnl
+dnl Runs a LIBRARY-config script and defines LIBRARY_CFLAGS and LIBRARY_LIBS
+dnl
+dnl The script must support `--cflags' and `--libs' args.
+dnl If MINIMUM-VERSION is specified, the script must also support the
+dnl `--version' arg.
+dnl If the `--with-library-[exec-]prefix' arguments to ./configure are given,
+dnl it must also support `--prefix' and `--exec-prefix'.
+dnl (In other words, it must be like gtk-config.)
+dnl
+dnl For example:
+dnl
+dnl    AC_PATH_GENERIC(Foo, 1.0.0)
+dnl
+dnl would run `foo-config --version' and check that it is at least 1.0.0
+dnl
+dnl If so, the following would then be defined:
+dnl
+dnl    FOO_CFLAGS to `foo-config --cflags`
+dnl    FOO_LIBS   to `foo-config --libs`
+dnl
+dnl At present there is no support for additional "MODULES" (see AM_PATH_GTK)
+dnl (shamelessly stolen from gtk.m4 and then hacked around a fair amount)
