/*
------------------------------------------------------------------------------------
NOTE:  For reasons of speed, I do not load the command processor in spawned
       shells by specifying the /n option in the start command.  This means that
       batch files will not run ( ie. TEX_EXEC=d:\mytex\texit.cmd ) since there
       is no interpreter!

       If you want to specify a batch file as the executable in a *.EXEC
       variable, then change the corresponding *_IS_CMD variable to 1.

       ie.  TEX_EXEC = 'd:\texit.cmd'
            TEX_IS_CMD = 1

       Do not use the ^&plain or ^&lplain argument in the start command when
       using batch files as the arguments will not make it through to the
       command.

       ie.  if you specify TEX_EXEC = 'd:\texit.cmd ^&lplain' then texit.cmd
       will not receive any arguments.  But, TEX_EXEC = 'd:\texit.cmd' works
       fine!

       I have no explanation for this weirdness!  Ask someone smarter.

       If you want to run a previewer that is not a PM application, add the
       switch /win or /fs as appropriate in the start commands in the command
       procedure 'texvw'.
