name 12many category Package shortdesc 12many, generalizing mathematical index sets longdesc In the discrete branches of mathematics and the computer sciences, longdesc it will only take some seconds until you're faced with a set like longdesc {1,...,m}. Only some people write $1\ldotp\ldotp m$, or $\{j:1\leq longdesc j\leq m\}$, and that journal you're submitting to might want longdesc something else entirely. \otm{} provides an interface that makes longdesc changing from one to another a one-line change.
