 The configuration file is located by finding the first
   readable instance of Filename in the following places:
   \begin{enumerate}
   \item the current directory (.)
   \item the immediate source directory (./src)
   \item a sibling source directory (../src)
   \item the directory specified by the M3CONFIG environment variable.
   \item the directory containing the current executable (if $argv[0]$
         contains any path elements)
   \item the directories named by the PATH environment variable.
   \end{enumerate}
