+## Verbose output
+
+Specific scripts can generate huge amount of output. These do use a function
+`$LogPrintVerbose`, which is declared, but has no code, intentionally.
+
+If you *really* want that output set the function to be the same as
+`$LogPrint`:
+
+    :set LogPrintVerbose $LogPrint;
+
+To revert that change just run:
+
+    :set LogPrintVerbose;
