Starting with Harvest Version 1.2 we began integrating support for summarizers based on outside ``component technologies'' of both a free and a commercial nature. The components distribution contains summarizers that are of interest to a more narrow audience (e.g., for extracting content from a particular seismological data format); are particularly large (e.g., summarizers where only the binary executables are being made available); or are just interface code to non-freely distributable systems (e.g., code for interfacing Harvest with a commercial database system that must be purchased from an outside organization).
The components are available from the components directory at the top-level of each of the Harvest distribution sites.
At present we only have a modest number of outside components. Specifically, we have added support for two popular PC data formats: Microsoft's Rich Text Format (RTF), and Framemaker's Maker Interchange Format (MIF). These summarizers are discussed below.
