Welcome

WorldTree Software is the home of JM Gustafson's software development projects. I have developed a wide range of applications from online games to web development tools and have also done some web site design.

The WorldTree Software motto, "Simple design, intense content" reflects my belief that software and web pages should be designed using a minimalist approach. This leads to ease of maintenance saving time and money, and ease of use providing for a better user experience.

FileQuery Release (8/30/2008)
The first version of FileQuery has been released. File Query is a command line interface you can use to search for files on your computer. You specify search criteria using File Query Language (FQL), which is similar to SQL. This allows you to specify complex search criteria to find exactly what you're looking for.

MathCmd Release (12/21/2007)
The first version of MathCmd has been released. This is a free Windows command line tool that allows you to enter mathematical expressions and see the results like a calculator, only easier. You can enter mathematical expression, define and use variables, and define custom functions. This is the first application in a family of math tools that will be released from WorldTree Software.

ModPro Release (11/9/2007)
The first public version of ModPro has been released. After more than two years of research and development I'm ready to let this web development tool out the door so others can use it. ModPro provides a way to develop web sites using modular programming. Instead of writing flat HTML files you define modules that can be shared across your web site. This makes it much easier to provide a consitent look and feel and maintain your web sites. All of the web sites I develop (including this one) are done with ModPro.
