No matter, if this means creating 305 * a new session (due to the second R without warning 306 * message), detching the session first (and due to the 307 * capitalised D logging out), or simply attaching to it. 308 * 13.07.95 -- 3.05.74 Markroutine learned new join mode: comma seperated. 309 * Can disable the detach feature from config.h. 310 * Configure.in now calls etc/toolcheck.
