Say what happens instead of making files do things

A file is written to; it does not write, score or name anything. Five comments
and doc lines said otherwise, two of them older than today.

   like it was never scored. The rules here follow the class: 5 points for a
   portable station, 2 for one in Region 1 at home and 3 from outside it.
 - **SA 10 and OK/OM DX on SSB** are not written in code at all: both are
-  published as `.udc` files, and the files score the station's logs to the
-  contact. N1MM's OK/OM DX class is the CW running only and says so; the SSB
+  published as `.udc` files, and with those files in the user-defined contests
+  folder the station's logs score to the contact. N1MM's OK/OM DX class is the CW running only and says so; the SSB
   running has different rules and its own pair of files, one for each side of
   the contest.
 - **A `.udc` section multiplier** is counted for any exchange that is not all
-  digits. N1MM checks it against the section list the file names in
-  `MultWindowType`, and those lists are not held here, so a US state sent into
-  an OK/OM DX log counts here and not in N1MM. Three contacts across the two
-  logs.
+  digits. N1MM checks it against the section list given in the file's
+  `MultWindowType` setting, and those lists are not held here, so a US state

+  contacts across the two logs.
 - **The BARTG Sprint** stores the time of the contact in the exchange column,
   which N1MM fills in by itself. Nothing here fills it in yet, so a log written
   here carries the serial number alone.
