The Perl HL7 Toolkit provides a simple but
flexible Perl toolkit for using the HL7 protocol.
The toolkit consists of a Perl API for
manipulating HL7 messages, an implementation of
a pluggable forking HL7 server for developing HL7
capable applications in Perl, and a queue daemon for polling non-HL7 queues, like database, filesystems, etc., and translating messages in these queues into HL7 (and vice-versa).
