      This Java Card SDK is the official SDK made available by Oracle for programming for the Java Card platform.

      Instructions for usage:

      First, compile your '.java' (NixOS-specific: you should not need to set the class path -- if you need, it's a bug):
          javacardc -source 1.5 -target 1.5 [MyJavaFile].java
      Then, test with 'jcwde' (NixOS-specific: you can change the java version used to run jcwde with eg. JAVA=jdb):
          CLASSPATH=. jcwde [MyJcwdeConfig].app & sleep 1 && apdutool [MyApdus].apdu
      Finally, convert the '.class' file into a '.cap':
          converter -applet [AppletAID] [MyApplet] [myPackage] [PackageAID] [Version]
