+1. Fix the small whoopsie in sh/dx.
+01Jun20=======================================================================
+1. Fix sh/dx iota and qra. This completes the conversion of sh/dx's limited
+ "old style" parsing to using Filter style parsing with something that
+ allows expressions include brackets ( and ) as well as the 'not' keyword.
+ NOTE: the precedence rules are the same as perl's '!', '||' and '&&'
+ operators.

+1. Improve links command layout slightly.
+2. Issue an *accurate* UPGRADE.mojo with all the new packages included!
+3. Fix issue with sh/dx
+30May20=======================================================================
+1. Fix sh/dx! It appears that there is a long standing problem with sh/dx not
+ actually return all the answers it should. I have also had a request to
+ allow / enable the "not" keyword (just like the filtering system dones).
+
+ Now this was one of the earliest modules that I wrote and it took quite
+ a bit of work to tease out the important bits and then use the Filter
+ module (as in acc/spot) to generate the sh/dx filtering expressions. This
+ seems to have been done.
+
+ NB This will likely not work if you are using a SQL backend to do sh/dx
+ commands. This was never actually an official feature. It is now
+ deprecated.

+1. Please install Math::Round and Data::Structure::Util. Instructions are
+ available in UPGRADE.mojo.
