# How to change PI name and footnote in NIH documentclass?

I am writing a proposal for a class and I am using \documentclass{nih} (http://www.ctan.org/tex-archive/macros/latex/contrib/nih/). However, for the name of the PI, it shows "Donald, Bruce R." by default. How can I change this name to my own? Also, how can I change the text in the footnote? It says "PHS 398/2590 (Rev. 09/04)" on the left and "Continuation Format Page" on the right. I only want the page number and leave out the other stuff. Here is a minimal example:

\documentclass[12pt]{nih}
\usepackage{lipsum}

\begin{document}

\section{Specific Aims}
\lipsum

\end{document}

-

The Principal Investigator name can be set with \piname; the two parts of the footer can be nullified by standard fancyhdr commands:

\documentclass[12pt]{nih}
\usepackage{lipsum}

\lfoot{}
\rfoot{}

\piname{Donald Duck}

\begin{document}

\section{Specific Aims}
\lipsum

\end{document}
