+The files in the "shared/" directory are used by all components
+inside the VPN plugin repository (src, properties, auth-dialog).
+
+The files in shared/nm-utils are copied from NetworkManager
+repository and used as is:
+Do *not* modify these files locally so that they don't diverge
+from their original. Fix/extend them in their respective origin
+first, and re-import the files as a whole.

+ * The boolean type _Bool is C99 while we mostly stick to C89. However, _Bool is too
+ * convinient to miss and is effectively available in gcc and clang. So, just use it.
+ *
+ * Usually, one would include "stdbool.h" to get the "bool" define which aliases
+ * _Bool. We provide this define here, because we want to make use of it anywhere.
+ * (also, stdbool.h is again C99).
+ *
+ * Using _Bool has advantages over gboolean:
+ *
+ * - commonly _Bool is one byte large, instead of gboolean's 4 bytes (because gboolean
+ * is a typedef for gint). Especially when having boolean fields in a struct, we can
+ * thereby easily save some space.
+ *
+ * - _Bool type guarantees that two "true" expressions compare equal. E.g. the follwing
+ * will not work:
+ * gboolean v1 = 1;
+ * gboolean v2 = 2;
+ * g_assert_cmpint (v1, ==, v2); // will fail
+ * For that, we often to use !! to coerce gboolean values to 0 or 1:
+ * g_assert_cmpint (!!v2, ==, TRUE);
+ * With _Bool type, this will be handled properly by the compiler.
+ *
+ * - For structs, we might want to safe even more space and use bitfields:
+ * struct s1 {
+ * gboolean v1:1;
+ * };
+ * But the problem here is that gboolean is signed, so that
+ * v1 will be either 0 or -1 (not 1, TRUE). Thus, the following
+ * fails:
+ * struct s1 s = { .v1 = TRUE, };
+ * g_assert_cmpint (s1.v1, ==, TRUE);
+ * It will however work just fine with bool/_Bool while retaining the
+ * notion of having a boolean value.
+ *
+ * Also, add the defines for "true" and "false". Those are nicely highlighted by the editor
+ * as special types, contrary to glib's "TRUE"/"FALSE".
