A.5. - Installing graphics filters
A number of precompiled graphics filters are included in the filters subdirectory. For those that produce output for a printer, you should create a spoolers file as described in the file filter_tools/spoolers. You also may wish to compile additional filters from the files in the filter_tools directory. Consult the README file in the filter_tools directory for more information. Compiled filters should be moved or copied to the filters directory.
