## What is it?

Ruby-HL7 is a library for parsing and generating HL7 2.x messages. HL7  
3.0 message support is planned for a future release. HL7 is a widely  
used medical information interchange format.

Feature list:

- flexible parsing support
- MLLP support
- provides a simple dsl for defining segments
- allows for arbitrary manipulation of segment data
- automatic segment ordering (via sort)
- familiar Array/Enumerable semantics
- easy associated/child segment access

## Changes

This release addresses a few bugs found with segment access,  
specifically null segment access and empty segment access.  
It also provides a speed improvement when parsing messages with many  
unimplemented/unknown segments.  
Associated/Child segment access has been implemented.

## How do I get it?

gem install ruby-hl7

or grab the tarbal from [http://rubyforge.org/frs/?group\_id=3261](http://rubyforge.org/frs/?group_id=3261)
