  The following procedures are provided in the Tcl library:
  .TP
  \fBauto_execok \fIcmd\fR
! Determines whether there is an executable file by the name \fIcmd\fR.
  This command examines the directories in the current search path
! (given by the PATH environment variable) to see if there is an
! executable file named \fIcmd\fR in any of those directories.
! If so, it returns 1;  if not it returns 0.  \fBAuto_exec\fR
  remembers information about previous searches in an array
  named \fBauto_execs\fR;  this avoids the path search in
  future calls for the same \fIcmd\fR.  The command \fBauto_reset\fR

  .TP
  \fBauto_execok \fIcmd\fR
! Determines whether there is an executable file or shell builtin
! by the name \fIcmd\fR.
! If so, it returns a list of arguments to be passed to \fBexec\fR 
! to execute the executable file or shell builtin named by \fIcmd\fR.
! If not, it returns an empty string.  
  This command examines the directories in the current search path
! (given by the PATH environment variable) in its search for an
! executable file named \fIcmd\fR.  On Windows platforms, the search
! is expanded with the same directories and file extensions as used
! by \fBexec\fR.

  remembers information about previous searches in an array
  named \fBauto_execs\fR;  this avoids the path search in
