+ About MMS and DCL
+ -----------------
+
+ MMS has certain limitations when it comes to line length, and DCL has
+ certain limitations when it comes to total command length. We do
+ what we can to mitigate, but there is the possibility that it's not
+ enough. Should you run into issues, a very simple solution is to set
+ yourself up a few logical names for the directory trees you're going
+ to use.
