Last change on this file since 22770 was 22770, checked in by ak19, 10 years ago

More changes for ticket 152: making the collectdir moveable. When using server.exe, if GLI was last shutdown when another collectdir was active, this needs to be read in from the user config.xml by GLI, and server.exe needs to use it.
