+ * version - helper functions for major.minor-style version numbers
+ *
+ * This code provides some helper functions to deal with version numbers in
+ * the form major.minor.
+ *
+ * Author: Peter Hutterer <peter.hutterer@who-t.net>
+ * Maintainer: Peter Hutterer <peter.hutterer@who-t.net>

+ *
+ * Example:
+ *	struct version a = version(1, 0);
+ *	struct version b = version(2, 2);
+ *
+ *	if (version_cmp(a, b) < 0)
+ *		printf("Feature supported in version 2.2 but we have %d.%d\n",
+ *			version_major(a), version_minor(a));
+ *
+ *	if (version_cmp(a, version(3, 4)) < 0)
+ *		printf("Feature only supported in version 3.4\n");
