+/*
+ * <sys/socket.h> for the MontaukOS git port.
+ *
+ * MontaukOS does have TCP -- the kernel exposes it as IPC handles through
+ * montauk::socket(), not as BSD descriptors -- but nothing bridges the two
+ * into the fd space that read()/write() use, and git's transports assume a
+ * descriptor it can hand to a sub-process. Until that bridge exists, every
+ * call here fails with ENOSYS, which surfaces as "unable to connect" from
+ * `git clone git://...` rather than as a crash.
+ *
+ * That leaves the local transports -- init, add, commit, log, diff, and
+ * clone/fetch/push against a path on disk -- which are what this port is for.
+ *
+ * Implementations in montauk-compat.c.
