This is the main module to be included by code using the Labeled IO (LIO) library. This module exports the core library (documented in LIO.Core), with support for labeled values (documented in LIO.Labeled) and privileges (documented in LIO.Privs).

Certain symbols in the lio library, particularly those in LIO.Exception, use the same names as their IO equivalents in the system libraries. Hence main modules that mostly include IO code and only need to invoke LIO code should import LIO.Run (or LIO.DCLabel) to avoid polluting their namespaces.

Most code will need to use a particular label format, which needs to be imported separately. For instance:

 import LIO
 -- Import your favorite label format:
 import LIO.DCLabel
