To install WML, get the latest version from www.thewml.org/sw/wml/distrib. As of this writing, the latest version was wml-2.0.8.tar.gz. Save the tarball in /tmp.
To build the software, unzip and untar the tarball in /tmp. Then, cd into the wml directory, run the provided configure program, and then make, test, and install in the usual manner. Only the last step need be done as root:
$ cd /tmp $ tar xzvf wml-2.0.8.tar.gz $ cd wml-2.0.8 $ ./configure $ make $ make test $ su # make install
Create a directory to work with WML:
$ mkdir /var/wwwl/wml $ chmod a+rx /var/wwwl/wml $ cd /var/wwwl/wml
