+% boolexpr : Purely expandable boolean expressions and switch (eTeX)
+%
+% The \boolexpr macro evaluate boolean expressions in a *purely expandable way*.
+%
+% \boolexpr{ A \OR B \AND C } expands to 0 if the logical expression is TRUE.
+%
+% A, B, C may be :
+%     - numeric expressions such as:  x = y,  x <> y,  x > y  or:  x < y
+%     - boolean switches:             \iftrue 0\else 1\fi
+%     - conditionals:                 \ifcsname whatsit\endcsname 0\else 1\fi
+%     - another \boolexpr:            \boolexpr{ D \OR E \AND F }
+%
+% \boolexpr may be used with \ifcase:
+%     \ifcase\boolexpr{ A \OR B \AND C }
+%           What to do if true
+%     \else
+%           What to do if false
+%     \fi
+%
+% \switch remains *purely expandable* (it may be used inside \csname...\endcsname f.ex.)
+%
+% \switch
+% \case{ boolean expression} to do in first case
+% \case{ boolean expression} to do in second case
+% \otherwise to do if no case were true
+% \endswitch

+%           etex boolexpr.dtx
+%    (c) If you insist on using LaTeX
+%           latex \let\install=y\input{boolexpr.dtx}
