-% \begin{documentation}
-%
-% There are a small number of \TeX{} or \LaTeXe{} concepts which are not used
-% in \pkg{expl3} code but which need to be manipulated when working as a \LaTeXe{}
-% package. To allow these to be integrated cleanly into \pkg{expl3} code, a set
-% of legacy interfaces are provided here.

-% \begin{function}[EXP,pTF]{\legacy_if:n}
-% \begin{syntax}
-% \cs{legacy_if_p:n} \Arg{name}
-% \cs{legacy_if:nTF} \Arg{name} \Arg{true code} \Arg{false code}
-% \end{syntax}
-% Tests if the \LaTeXe{}/plain \TeX{} conditional (generated by \tn{newif})
-% is \texttt{true} or \texttt{false} and branches accordingly. The
-% \meta{name} of the conditional should \emph{omit} the leading \texttt{if}.
-% \end{function}

-% \begin{function}[added = 2021-05-10]

-% \legacy_if_set_true:n, \legacy_if_set_false:n,
-% \legacy_if_gset_true:n, \legacy_if_gset_false:n

-% \begin{syntax}
-% \cs{legacy_if_set_true:n} \Arg{name}
-% \cs{legacy_if_set_false:n} \Arg{name}
-% \end{syntax}
-% Sets the \LaTeXe{}/plain \TeX{} conditional |\if|\meta{name}
-% (generated by \tn{newif}) to be \texttt{true} or \texttt{false}.
-% \end{function}
-%
-% \begin{function}[added = 2021-05-10]{\legacy_if_set:nn, \legacy_if_gset:nn}
-% \begin{syntax}
-% \cs{legacy_if_set:nn} \Arg{name} \Arg{boolexpr}
-% \end{syntax}
-% Sets the \LaTeXe{}/plain \TeX{} conditional |\if|\meta{name}
-% (generated by \tn{newif}) to the result of evaluating the
-% \meta{boolean expression}.

-% A friendly wrapper. We need to use the \cs{if:w} approach here, rather than
-% testing against \tn{iftrue}/\tn{iffalse} as the latter approach fails for
-% primitive conditionals such as \tn{ifmmode}. The \cs{reverse_if:N} here
-% means that we get a slightly more useful error if the name is undefined.
