libkar is an extremely simple Qt based keyed archiver for usage by the KISS IDE suite of applications. This is a separate library because it is used as a data interchange format between applications in the suite.
cd libkar
mkdir build
cd build
cmake ..
make && make install
Kiss::Kar *archive = Kiss::Kar::create();
archive->addFile("hello.txt", "Hello, World!\n");
archive->save("test.kar");
delete archive;
