+ * \brief hg_outgoing command for hglib API.
+ * 
+ * Show changesets not found in the specified destination repository or the

+ * push was requested.
+ *
+ * See pull for details of valid destination formats.
+ *
+ * Options/Argument list option:
+ *
+ *	-f, --force	run even when the destination is unrelated
+ *	-r, --rev		a changeset intended to be included in the 
+ *				destination
+ *	-n, --newest-first	show newest record first
+ *	-B, --bookmarks	compare bookmarks
+ *	-b, --branch	a specific branch you would like to push
+ *	-p, --patch	show patch
+ *	-g, --git		use git extended diff format
+ *	-l, --limit	limit number of changes displayed
+ *	-M, --no-merges	do not show merges
+ *	--stat		output diffstat-style summary of changes
+ *	-G, --graph	show the revision DAG
+ *	--style		display using template map file
+ *	--template		display with template
+ *	-e, --ssh		specify ssh command to use
+ *	--remotecmd	specify hg command to run on the remote side
+ *	--insecure		do not verify server certificate (ignoring 
+ *				web.cacerts config)
+ *	-S, --subrepos	recurse into subrepositories
+ *	aliases: out
+ *
+ * To get outgoing information use the returned hg_csetstream_buffer structure 
+ * with hg_fetch_cset_entry function.
+ *
+ * \param handle The handle of the connection, wherewith I want to communicate
+ * \param callback A function that will handle error data. 
+ *                 A NULL pointer will ignore error data.
+ * \param argument The option list. Will contain all option that you wish.
+ * \retval hg_csetstream_buffer A pointer to hg_csetstream_buffer structure if 
+ *                              successful
+ * \retval NULL to indicate an error, with errno set appropriately.
