NeoTool Development, LLC [http://www.neotool.com/] develops
applications for the health-care industry.  They focus on
HL7 and [Cloverleaf] in networking ...

(... and Cloverleaf, for those wondering about the Tcl connection, uses Tcl extensively as an internal scripting language. It used to use Tk for its GUIs, but I think most of them have been rewritten in Java. Pity. --[Bryan Oakley])

[[What are HL7 and Cloverleaf?]]

Cloverleaf is a product of Quovadx (which aquired Healthcare.com, which was formerly known as HDIE, which aquired Healthcare Communications, the originator of the product). Cloverleaf is an "integration engine".  

HL7 is a format for data interchange in the healthcare industry.

For the time being, some of this information may still be available at http://www.healthcare.com.
