% boolexpr : Purely expandable boolean expressions and switch (eTeX - v3.1 2009/09/30)
%
% 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
%
% \switch may have an optional argument to repeat in each \case evaluation, e.g. :
%
% \switch[\value{myCounter}]
%      %|--|        --------------------------------------------------->   |--|
% \case{>=12}It's $>=12$% => \case will expand to : \case{\value{myCounter}>=12}
% \case{=1}It's $1$%      => \case will expand to : \case{\value{myCounter}=1}
% \otherwise ...
% \endswitch
%
% or : *(NB the double curly braces)*
% \switch[\pdfstrcmp{dummy}}]
%      %|-----|   ------------------------------------------------>  |-----|
% \case{{first}}It's "FiRsT"% => \case{\lowercase{\ifstrequal{dummy}}{first}}
% \case{{second}}It"s "SeCoNd"%=> \case{\lowercase{\ifstrequal{dummy}}{second}
% \endswitch

%           latex \let\install=y\input{boolexpr.dtx}
