Running Lisp on Linux

Where does Linux keep `graphical-read-eval-print-loop` stuff?
It worked fine on Windows.

At least Windows doesn't rip program into "bin shared home include lib man" bits. To install a Windows prog it's enough to unzip it and import *.reg file.

At least Unix doesn't rip program into "HKEY_LOCAL_MACHINE HKEY_CURRENT_USER HKEY_CLASSES_ROOT HKEY_USERS HKEY_CURRENT_CONFIG" bits. To install an Unix prog it's enough to untar it and make the Makefile.
