Hi, I noticed that the documentation needs an update regarding the install_tree macro - the parameter is not enlisted in the "How to become a ptxdist guru" document. I would suggest either to reference the description of install_copy, parameter 7, or to add a few lines in the install_tree documentation itself. In both cases, the synopsis of install_tree (chapter 5.2.4) should be changed from $(call install_tree, , , , , ) to $(call install_tree, , , , , [, ]) Cheers, Stefan
