These are compiled binaries for a 64 bit system.  They are static
compiles and benefit from having gnuplot available for full functionality.

In Linux:

The install directory will be:
/usr/local

If you are root and unzip in / directory, it will put everything
in /usr/local

usr
└── local
    ├── bin
    ├── include
    ├── lib
    └── share
        ├── doc
        │   └── bsu
        ├── man
        │   ├── man1
        │   ├── man3
        │   ├── man5
        │   └── man7
        ├── octave
        │   └── site-m
        └── scripts
On the otherhand, if you are worried, just find some place
safe to unzip, and then manually move stuff where you want it.
