sh or bash to run?

[nlw0]

I tried to run the program like the README file says, using /bin/sh, but got a syntax error. It seems to work after I tried bash instead...

nlw@kvelertak:~/src/lenskit-hello$ /bin/sh build/install/lenskit-hello/bin/lenskit-hello 72
build/install/lenskit-hello/bin/lenskit-hello: 158: build/install/lenskit-hello/bin/lenskit-hello: Syntax error: "(" unexpected
nlw@kvelertak:~/src/lenskit-hello$ bash build/install/lenskit-hello/bin/lenskit-hello 72

Evidently it should be bash - thanks!
