This is the map of SIPB drawer assignments. Assignments themselves are stored in assignments.csv. The first column is the drawer itself. The second column is a category of assignment -- "used" for an assigned drawer, "free" for an unallocated drawer, and "opening" for drawers that have been relinquished but not yet cleared out, and "sipb" for drawers with a general SIPB-wide usage. The third column is the specific person or use it has. To update the PDFs, run "make".
