* name Name of shell.
* path Location of shell. Overrides "name" if given

* is TRUE or template of command to execute a
* command so as to ignore any errors it returns if
* hasErrCtl is FALSE.
* builtins A space separated list of builtins. If one
* of these builtins is detected when make wants
* to execute a command line, the command line is
* handed to the shell. Otherwise make may try to
* execute the command directly. If this list is empty
* it is assumed, that the command must always be
* handed over to the shell.
* meta The shell meta characters. If this is not specified
* or empty, commands are alway passed to the shell.
* Otherwise they are not passed when they contain
