 \subsection{The execution environment for component programs}
 
   A SwiftScript \verb|app| declaration describes how a component

   A program is invoked in its own working directory; in that working
-directory, the program can expect to find all of the files that are
-passed as inputs to the application block; and on exit, it should leave
-all files named by that application block in the same working
-directory. Programs should not make excessive(?) assumptions about
-their working environment; for example, they should not assume that

 they will be executed on a particular host (to facilitate site
