allow setting the exit code

[benwbooth]

It would be useful to be able to signify an exit code from within the script using a global variable or something, such as *exit-code*. Then when lein exec is called, the script sets the variable, and when lein exec exits, it uses the value of the variable as its exit status.

Does (System/exit 1) work for you? You can use any error code you want.

Ah, I discovered that leiningen already supports this behavior with the leiningen.core.main/exit function.
