The applications all read and/or write finite element databases stored in the \exo{}~\cite{bib:exodus} format. Each application is targeted at a few specific areas of functionality: \begin{description} \item[\exodiff] compares the results data from two \exo{} files with user-specified relative or absolute tolerances. \item[\epu] combines multiple \exo{} databases produced by a parallel application into a single \exo{} database. \item[\ejoin] joins two or more \exo{} databases into a single \exo{} database. The input databases must have disjoint meta and bulk data. \item[\conjoin] joins two or more \exo{} databases into a single database. The input databases should represent the same model geometry with results data written sequentially. \end{description} %\end{titlepage}
