 /**
+ * \brief hg_identify command for hglib API.
+ *
+ * Print a summary identifying the repository state at REV using one or two
+ * parent hash identifiers, followed by a "+" if the working directory has
+ * uncommitted changes, the branch name (if not default), a list of tags, and a
+ * list of bookmarks.
+ *
+ * When REV is not given, print a summary of the current state of the
+ * repository.
+ *
+ * Specifying a path to a repository root or Mercurial bundle will cause lookup
+ * to operate on that repository/bundle
+ *
+ * Options/Argument list option:
+ *
+ *	-r, --rev		identify the specified revision
+ *	-n, --num		show local revision number
+ *	-i, --id		show global revision id
+ *	-b, --branch	show branch
+ *	-t, --tags		show tags
+ *	-B, --bookmarks	show bookmarks
+ *	-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)
+ *	aliases: id
+ *
+ * \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 unparse_data  To indicate the end of identify_command.
+ * \retval NULL To indicate an error.
+ *
+ * errno can be:
+ *      - hg_rawcommand errors
