[NTG-context] parbox equivalent?

[jazz_johnson at verizon.net]

Is there any recommended ConTeXt equivalent to latex's parbox command?

Specifically I'm thinking of signature blocks such as

\vspace{1in}
   \hspace{2.5in}
      \parbox{3in}{Sincerely yours,
                                 \vspace{.7in}\\
                                John Doe}

or this:

\newcommand{\signature}{ %
   \vspace{1in}\hspace{3.0in}%
   \begin{minipage}[t]{3.5in}%
      The Board of Directors 
      \vspace{.1in}\\By:%
      \begin{minipage}[t]{3.0in}%
         \includegraphics[width=2.5in]{gm_signature.png}\\%
         \vspace{-1 cm}%
         \parbox[t]{3.0in}{\hrulefill\\John Doe, General Manager}%
      \end{minipage}%
   \end{minipage}%
}

or this:
\begin{tabular}{p{3in} p{3in} }
\signatureblock1 & \signatureblock2 \\
\notaryblock1       & \notaryblock2       \\
\stop{tabular}

Thanks
