*** IMPORTANT: TWO CHANGES THAT ARE NOT UPWARDLY COMPATIBLE ***
(1) The @Abstract symbol in technical reports now comes before the
// symbol, not after it. See User's Guide for details.
(2) Setup file arrangements have changed. You now need to have one
@SysInclude line for each package you use. For example,
Previous versions Version 3.13
---------------------------------------------
@SysInclude { eq } @SysInclude { eq }
@SysInclude { ddoc } @SysInclude { diag }
@SysInclude { doc }
Import clauses in mydefs files also have to change:
Previous versions Version 3.13
---------------------------------------------
import @DocumentLayout import @BasicSetup
import @CPrint import @CPSetup
import @DiagramPrint import @DiagSetup
Sorry for the inconvenience, but the old system was inconsistent
and was tending towards an unsustainable combinatorial explosion
of setup files. No changes *within* documents are needed, and
these new arrangements do not affect the content of the packages.
The user's guide documents it all.

@DoubleLine symbol in diagrams for drawing a double line
-l and -L flags for selecting collation order (see lout -u)
