Shebang lines are much less useful than they appear because they only
split on the first space. Consider the following script:
#!/usr/bin/env python -tt
print "hello, world"
Running it gives the error because env is given the single argument
("python -tt") instead of two arguments ("python" and "-tt"):
/usr/bin/env: python -tt: No such file or directory
