import(+PredicateIndicator, 
...)Import predicates PredicateIndicator into the current context 
module. PredicateIndicator must specify the source module 
using the <module>:<pi> construct. 
Note that predicates are normally imported using one of the directives use_module/[1,2]. 
The import/1 
alternative is meant for handling imports into dynamically created 
modules. See also export/1 
and export_list/2.
