A small kit is provided in the /usr/opt/nscldaq/VERSION/filterkit directory. All of the source code needed to build a fully functional filter program is provided in this directory. It is recommended that the user start with these files to begin the process of creating his/her filter program. Simply copy the entire directory to a working location or the relevant files: Makefile, SkeletonMain.cpp, and CTemplateFilter.cpp. I will explain the contents of each of these files in the following sections.
