PAML web siteThis site provides some old versions of paml, for special purposes or historical reasons. In general, you are advised to use the most recent version, which should have fixed some old bugs and introduced new bugs. The archives posted here include the win32 executables as well as C source codes, which you can compile for MAC OS or unix/linux. Look for files such as Makefile.UNIX and readme.txt in the folder src/ for compiling instructions. Very old versions have all files in one folder, in which case, you should look at the Makefile or files like paml.cc or paml.gcc for compiling commands and instructions.
Make sure to save the file as *.tar.gz (or some other right name such as .tgz) instead of *.tar.tar.
