The OMSORT library is a set of functions for sorting OmniMark shelves by key or value.
The OMSORT library is packaged as a module. To use OMSORT, you must import the OMSORT module into your program using a statement like this:
import "omsort.xmd" prefixed by sort.
Note that the prefix "sort.", which is attached to all functions, constants, and opaque data types exported by this library, is set in this statement and can be changed. For readability, we recommend that you always use the standard prefix when importing modules supplied by OmniMark.
