The various \function{exec*()} functions take a list of arguments for
the new program loaded into the process. In each case, the first of
these arguments is passed to the new program as its own name rather
than as an argument a user may have typed on a command line. For the
C programmer, this is the \code{argv[0]} passed to a program's
\cfunction{main()}. For example, \samp{os.execv('/bin/echo', ['foo',
'bar'])} will only print \samp{bar} on standard output; \samp{foo}
will seem to be ignored.
