+Contains the selection of the c & c++ compilers on z/OS. There are several
+different c compilers on z/OS, all of them are optional, so the correct
+one needs to be chosen based on the users input. This is compatible with
+the following compilers:
+
+IBM C/C++ For Open Enterprise Languages on z/OS 2.0
+IBM Open XL C/C++ 1.1 for z/OS
+IBM XL C/C++ V2.4.1 for z/OS 2.4 and 2.5
+IBM z/OS XL C/C++
