Dear all,

We are glad to announce the release of a new tool to manage HDF files. The  
background of the release of this exciting tool called HDFql is as  
follows:

Researchers, engineers, data managers, and students using the data format  
HDF currently waste a lot of unnecessary time managing HDF files. That is  
because to date, the APIs available for HDF have been highly complex. With  
HDF becoming increasingly common in the big data arena, a faster and  
simpler solution is needed.

Imagine being able to handle HDF files with a language as easy and  
powerful as SQL. Today this becomes a reality via our release of the  
freeware HDFql.

HDFql stands for "Hierarchical Data Format query language" and is the  
first tool that enables users to manage HDF files through a high-level  
language. Not only that, HDFql allows users to both read and write HDF  
files across a variety of operating systems and programming languages  
(Windows, Linux, OS X; C/C++, Java, Python, C#).

HDFql was designed to be simple to use and similar to SQL, thus  
dramatically reducing users' learning effort and time needed to manage HDF  
files.
