The igpp-docgen tool is a document generator based on Apache Velocity. The tool can process template documents written in Velocity Template Language (VTL). It can read PDS3 labels, text files containing keyword=value pairs, spreadsheets in CSV or TAB format and metadata in CDF files. The content of each processed files are assigned to variables in separate Velocity contexts (namespaces) and can be referenced in the Velocity template file. The output format can be text files, including well-formed PDS3 or XML.
The igpp.docgen tool was developed using Java and will run on any platform with a supported Java Runtime Environment (JRE). The software was specifically developed under Java version 1.6 and has only been tested with this version. You can determine which version of Java you are running with the command:
