The source code archive is a repository of zip files containing source code, build.xml files, build.gradle files, SQL scripts (as necessary), and other relevant files for most of the monthly presentations. Each zip file corresponds to a monthly meeting, and is named with the format, jsigγγμμ.zip, where γγ represents the two-digit year and μμ represents the two-digit month. Each project has been built with Ant, and/or Gradle, Java-based build tools for compiling and running Java applications (and a whole lot more), and has also been established within IntelliJ IDEA.
