Abstract: This note describes a Macaulay2 package for handling divisors.Group operations for divisors are included.There are methods for converting divisors to reflexive or invertible sheaves.Additionally, there are methods for checking whether divisors are Cartier, -ޑCartier, simple normal crossings, or generate base point free linear systems, or satisfy numerous other conditions.
