The back end and libraries are now up for general testing on a variety of boxes and operating systems.
The tarball is usually updated as the web page is. To download and install g95 on unix systems,
run the following command (originally from Joost Vandevondele):
wget -O - http://ftp.g95.org/g95-x86-
linux.tgz | tar xvfz -
This will create a directory named 'g95-install' in the current directory.
Run (or better yet make an appropriate symbolic link to) ./g95-
g95 in order to run g95.
