Unpacking ".tgz" Tarball Files
SimpleScalar software is distributed in GZIP'ed TAR format, often called "tarballs".  These are compressed archive files containing multiple directories of source code and data files.

To unpack a tarball on a Unix machine:

gunzip -c <tgz_file> | tar -xvf -

where <tgz_file> is the distribution tarball file name.  If the system complains that "gzip" is not found, you will need to install this utility.  It is available here from the Free Software Foundation.

To unpack a tarball on a Windows machine:

The free utilities WinZip or ZipGenius can unpack GZIP'ed TAR format files under Windows.
