+Example configuration for EleBBS-Win32
+--------------------------------------
+(provided by Mike Ehlert, aka pcm)

+Ext ctl file    No
+Batch           Yes

+You will need to have the environment variable DSZLOG set to DSZ.LOG.
+It should *not* have a path of course, so that it's created in the current
+nodes directory.
+
+Once you define that under control panel > system > env variables > system
+variables, be sure to close the window running eleserv or telsrv and reopen
+it for the environment variable to become active.. Otherwise there will be
+no log of the transfer and EleBBS will assume it failed.
