From the developer:
LibSBML is a free, open-source programming library to help you read, write, manipulate, translate, and validate SBML files and data streams. It's not an application itself (though it does come with example programs), but rather a library you embed in your own applications.
You may want to check out more software, such as ScanRouter Administration Utility, Short Empire for FSX or FS2004 or GnuWin32: GetText, which might be similar to libSBML.
