+This file contains the files associated with the various chaos
+down-loadable PDP11 systems. The following format MUST be
+observed for the PDP-10 side to win: Anything before a control-L
+is considered comments. After the control-L, the following
+sequence notes the beginning of a CHAOS ADDRESS-BIN FILE pair:
+<carriage return><line feed><plus sign> Following are 6
+octal digits, which comprise the 16 bit CHAOS address of the
+concentrator then a <colon>, then by the site name, another
+colon, and finally the filename topped off by a <carriage
+return>. The end of the site/filename pairs is accomplished by
+end-of-file, but it is a good idea to put something there, such
+as a control-L to make sure there is a <carriage return> after
+the last pair.
