The files in this directory, except this README itself, have been copied from the AsciiDoc 7.1.2 source package. In the past, we have hit annoying incompatibilities when people have attempted to rebuild ELinks documentation with new versions of AsciiDoc: http://bugzilla.elinks.cz/show_bug.cgi?id=989 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=491820 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=526349 So now we bundle the necessary files from a known good version to let ELinks documentation be built with them regardless of which version has been installed on the machine. This should keep things working as long as the Python interpreter remains compatible.
