+       character descriptions has come to  light,  which  identifies  them  as
+       VT100 special characters.
+
+       The DEC Special Character and Line Drawing Set (VT100) is indexed by an
+       ASCII character in the range 96 (`) to 126 (~).  That  index  character
+       is  part  of  the  definition  for  the curses ACS_ symbols.  The VT100
+       special characters can be categorized in three groups:
+
+       o   useful graphic symbols with a  standard  ACS_  symbol,  (e.g.,  the
+           line-drawing symbols),
+
+       o   possibly useful characters (these non-standard symbols),
+
+       o   representations  of  control characters (e.g., newline and vertical
+           tabulation).
+
+       A few ACS_ symbols do not  fit  into  DEC's  VT100  scheme.   The  AT&T
+       Teletype  5410v1  arrow  symbols  and ACS_BLOCK use indices outside the
+       range 96 to 126.  Two of the  Teletype  symbols  use  indices  in  that
+       range, with different meaning versus the VT100:
+
+       o   ACS_BOARD corresponds to the VT100 symbol for newline
+
+       o   ACS_LANTERN corresponds to the VT100 symbol for vertical tabulation
+
+       AT&T defined ACS_ names for the most useful graphic symbols, as well as
+       for its own.  Its header file commented:
+
+       /*
+        * Standard alternate character set.  The current ACS world is evolving,
+        * so we support only a widely available subset: the line drawing characters
+        * from the VT100, plus a few from the Teletype 5410v1.  Eventually there
+        * may be support of more sophisticated ACS line drawing, such as that
+        * in the Teletype 5410, the HP line drawing set, and the like.  There may
+        * be support for some non line oriented characters as well.
+        *
+        * Line drawing ACS names are of the form ACS_trbl, where t is the top, r
+        * is the right, b is the bottom, and l is the left.  t, r, b, and l might
+        * be B (blank), S (single), D (double), or T (thick).  The subset defined
+        * here only uses B and S.
+        */
+
+       Although these less-useful graphic symbols were not given  names,  they
+       were  used  in  terminfo entries.  The ncurses developers invented ACS-
+       prefixed names for them.
