考虑以下代码片段：
a) 使用命令在某些文档中打印文本\defPrimitiveRoots
\Snippet{\defPrimitiveRoots}{Integers with primitive roots}{
Let $n,k$ be integers, and $p$ a prime. Then $n$ possesses primitive roots if and only if $n$ is of the form $2, 4, p^k$ or $2p^k$.
}
b) 进一步呼吁\srem
\newcommand{\Snippet}[3]{
\newcommand{#1}{
\srem{#2}{
#3
}
}
}
c) 进一步呼吁保护\shadedrem环境。
\newcommand{\srem}[2]{
\begin{shadedrem}
\textbf{#1} \newline #2
\end{shadedrem}
}
最后，在文档中，文本被写入
\defPrimitiveRoots
我想要自动生成两个命令 1) \cshPrimitiveRoots（与 相同\defPrimitiveRoots above）和 2)\beaPrimitiveRoots其中文本被格式化以便它可以很好地打印在beamer幻灯片上。
问题：我想我必须更改这部分代码
\newcommand{\Snippet}[3]{
\newcommand{#1}{
\srem{#2}{
#3
}
}
}
类似于：
\newcommand{\Snippet}[3]{
% #1 = defPrimitiveRoots this should become cshPrimitiveRoots
% PrimitiveRoots is of course a variable.
\newcommand{#1}{
\srem{#2}{
#3
}
}
% #1 = defPrimitiveRoots this should become beaPrimitiveRoots
\newcommand{#1}{
% I know how to do setup for beamer slide here.
}
}
这是怎么做到的？

\documentclass{article}

% PrimitiveRoots is of course a variable.

\@namedef{bea#1}{%
