% Definition List:  A definition list is essentially the same as a description
% list, except that there is a required argument specifying the indentation to
% be used, and the list items are left-justified in the item columns, rather
% than right-justified.

\newcommand{\definitionlabel}[1]{\bf #1\hfill}
\newenvironment{definition}[1]{\begin{list}{}{\setlength{\labelwidth}{#1}
\setlength{\leftmargin}{\labelwidth}\addtolength{\leftmargin}{\labelsep}
\renewcommand{\makelabel}{\definitionlabel}}}{\end{list}}
%
% Reference List:  A list of references is formatted with no item label, the
% first line of text flush left, and all subsequent lines in the reference
% indented a few spaces to the right (like ApJ references).
