-\noindent This is a list of all corrections made to {\sl Computers \&
-Typesetting}, Volumes A,~B, C, and D\null, between 1 January 1991 and
-15 March 1992.
-Corrections made to the softcover version of {\sl The \TeX book\/} are
-the same as corrections to Volume~A\null. Corrections to the softcover
-version of {\sl The \slMF\kern1ptbook\/} are the same as corrections
-to Volume~C\null. Some of the corrections below have already been made in
-reprintings of the books. Changes to Volume~B refer to the fourth printing
-(1991), which differs markedly from earlier printings because it includes
-all the revisions for \TeX3.0. Changes to Volume~D refer to the third
-printing (1991), which differs markedly from earlier printings because
-it includes all the revisions for \MF\kern1pt2.0. Changes to the mini-indexes
-and master indexes of Volumes B and~D are not shown here unless they are
-not obviously derivable from what has been shown.
-Dozens of changes, too many to list
-here, have been made to Volume~E because of recent upgrades to the
-Computer Modern font source files.
-Those changes, which affect only the digitization at
-low resolution and the appearance of lowercase delta and
-some characters in the math symbols
-fonts (but not the {\tt TFM} files), are documented at
-the end of file {\tt cm85.bug}.

-Some ^{German} words traditionally change their spelling
-when they are split between lines. For example, `backen' becomes `bak-ken'
-and `Bettuch' becomes `Bett-tuch'. How can you instruct \TeX\ to produce
-such effects?

-stands for zero or more \<assignment>
-commands other than |\setbox|.
-If the assignments are not followed by a \<character>, where
-\<character> stands for any of the commands just discussed in the previous
-paragraph, \TeX\ treats |\accent| as if it were |\char|, except that
-the space factor is set to 1000. Otherwise the character that follows
-the assignment is accented by the character that corresponds to the
-\<8-bit number>. \ (The purpose of the intervening assignments is to
-allow the accenter and accentee to be in different fonts.) \ If the
-accent must be moved up or down, it is put into an hbox that is
-raised or lowered. Then the accent is effectively superposed on the
-character by means of kerns, in such a way that the width of the accent
-does not influence the width of the resulting horizontal list.
-Finally, \TeX\ sets |\spacefactor=1000|.

-`|}|' may be followed by
-optional \<assignment> commands other than |\setbox|,
