%% The `\CheckbidiVersion' and `\CheckxepersianVersion` macros
%% allows you to check for bidi and xepersian packages version,
%% respectively and execute code conditionally according to the version
%% number of each package. The macros accept four arguments:
%%
%% * The first argument is any of the three relation `<', `>', and `='.
%% * The second argument is the version number that you want
%% to compare with the actual package version number.
%% * The third argument is the `true code'.
%% * The last argument is the `false code'.
%% Here we check that if \bidiversion=15.2, if this is true,
%% we typeset `true' and otherwise `false'.
\CheckbidiVersion{=}{15.2}{true}{false}
%% Here we check that if \xepersianversion>14.2, if this is true,
%% we typeset `true' and otherwise `false'.
\CheckxepersianVersion{>}{14.2}{true}{false}
