Generating multiple versions of a document using a command inside \ifthenelse

Question

I'd like to be able to generate different versions of a document using some kind of print command inside an \ifthenelse statement. Here's an example of what I would like to do. I'd like to do it this way because my document is quite long and has many sections. I think it would be easier for me to do something like this rather than define all the text inside the \ifthenelse statement.

\documentclass{article}

\usepackage{ifthen}

\begin{document}

\newcommand{\docVersion}[1]
{
% normally, text would go where the commands \printA{} and \printB{} would go
    \ifthenelse{\equal{#1}{group A version}}{\printA{}}{}
    \ifthenelse{\equal{#1}{group B version}}{\printB{}}{}
}

% so here, I could define that I want group A's version
\docVersion{group A version}

% and only this would be printed
\printA{Some stuff for group A here.}

% and this would not
\printB{Some stuff for group B here.}

% and this would be printed also
Some stuff for both groups here.

\end{document}
