/**

 *
 * This is some _Markdown documentation_ in a
 * `source file`.

int main(int argc, char *argv[]) {
    printf("hello, world");
    return 0;
}

I recently posted an entry on my Jatalog project, which is a Java implementation of the Datalog deductive database system. I thought I could elaborate on why I created it.
