In the next release, "make install" will install not only the txr executable, but two hard links to it named txrlisp and txrvm.
When the executable finds that its name ends in "lisp" it will behave as if the --lisp option had been given.
Likewise, when it finds that its name ends in "vm", it will behave as if --compiled had been given.
This is useful in hash bang scripting situations in which you can't have any argument, and you don't want a suffix on the file:
#!/usr/bin/env txrvm... compiled code here ..
