If you want to build JRaceman yourself, or just look at the source code, you will have to unpack the source files from the src.zip archive file with the commands
cd jraceman-N_N_N; unzip src.zip
This will create a src directory with all of the Java files, as well as adding a few other files (such as a Makefile) to your jraceman directory.
Similarly, if you want to look at the Javadoc-generated API documentation for the Java classes, you must first unpack those html files from the apidoc.zip archive file with the commands
cd jraceman-N_N_N; unzip apidoc.zip
This will create the directory doc/api with all of the API documentation in it. Alternatively, you can unpack src.zip and then run the command
make doc
to run javadoc and create the API documents from the source files.
The JRaceman kit does not include the source to the Mckoi database. You can download the Mckoi database source from the Mckoi web site, or from the same location from which you downloaded JRaceman. You do not need the Mckoi source to compile JRaceman; the mckoidb.jar file included in the JRaceman kit is sufficient.
The JRaceman kit does not include the source to the jRegistryKey package. You can download the jRegistryKey source from the jRegistryKey web site, or from the same location from which you downloaded JRaceman. You do not need the jRegistryKey source to compile JRaceman; the jRegisgtryKey.jar file included in the JRaceman kit is sufficient.
