After obtaining the file perlgp-X.Y.Z.tar.gz (where X, Y and Z are version numbers), unpack it with one of the following command sequences on most Unix-like systems:
linux> tar xzf perlgp-X.Y.Z.tar.gz or unix1> gtar xzf perlgp-X.Y.Z.tar.gz or unix2> gunzip perlgp-X.Y.Z.tar.gz unix2> tar xf perlgp-X.Y.Z.tar
Then cd into the newly created directory named perlgp-X.Y.Z and follow the instructions in the README file for starting to work with the PerlGP system. Before you download, you may take a look at this README file in the following section.
