The OpenTxl Turing+ source code and build process for Unix-like systems OpenTxl requires the Turing+ compiler, tpc, to build. To build the fully checked debugging version of TXL in pure Turing+, use the command "make" in this directory. Tests can be run in the test/ subdirectory. Run "make" in that directory for a basic functionality test, and run "make" in the test/regression/ subdirectory for a full regression test. See the README.txt files in those directories for further information. To build the fast production version of TXL using auto-generated C code, first use the command "make csrc" in this directory to make the auto-generated C directory "csrc", then see the README.txt file in that directory for production build instructions.
