The Unix version comes in two forms - one linked dynamically against the Qt libraries, and one linked statically. The latter is of course somewhat bigger, so if you already have a copy of the Qt run-time libraries installed, then you would probably prefer the dynamically linked version.
If you haven't already done so, unzip and untar the package. The command ``tar -xvzf stode-x.y.tar.gz'' should do the trick (substitute x.y with the version number as appropriate).
The executables need to be copied somewhere where the PATH environment is set. Usually /usr/local/bin is a good choice (make sure it's in your path). The executables should have execute permission (the command ``chmod 755 file'' will do the trick). The run control files should be copied to your home directory (as .stoderc and .stodeqrc) or to /etc (as stoderc and stodeqrc). A directory in which to store the data files should be created. A directory ``stode''under your home directory is a good choice for this, since this is where the executables will look for them if they are not in the directory from which the executables are run and if the full path to the data files is not given.
All of the above can be done manually, or the bash script ``install.sh'' will do all of that for you. This allows a local, global or hybrid local/global installation, the latter probably being what most users want.
After installation, edit the run control and sample data files to suit your needs.
