1This is the developer's directory. Files here are not necessary to 2build libmarpa. They are necessary if you want to change the code. 3 4Special tools (such as Cweb) are required. These tools are all free, 5readily available, and highly portable. *But* these tools are not 6included. It may not be easy or even possible to install all these 7tools on some of the systems to which libmarpa, Marpa or Marpa::XS 8can be ported. 9
