Calc is distributed under the terms of the GNU Lesser General Public License. In the same section 0, one also find the following: For a library, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the library. There are at least two calc binary link libraries found in calc: libcalc.a libcustcalc.a Clearly all files that go into the creation of those binary link libraries are covered under the License. The ``scripts used to control compilation and installation of the of the library'' include: * Makefiles * source files created by the Makefiles * source code used in the creation of intermediate source files All of those files are covered under the License. The ``associated interface definition files'' are those files that: * show how the calc binary link libraries are used * test the validity of the binary link libraries * document routines found in the binary link libraries * show how one can interactively use the binary link libraries Calc provides an extensive set of files that perform the above functions. * files under the sample sub-directory * files under the help sub-directory * files under the lib sub-directory * the main calc.c file The ``complete source code'' includes ALL files shipped with calc, except for the exception files explicitly listed in the ``Calc copyrights and exception files'' section below. -=- Calc copyrights and exception files ----------------------------------- With the exception of the files listed below, Calc is covered under the following GNU Lesser General Public License Copyrights: Copyright (C) year David I.

One of those times is when there is significantly similar versions available that are not covered under a Copyleft such as the GNU General Public License. The reason why calc was placed under the GNU Lesser General Public License is because for many years (1984 thru 1999), calc was offered without any form of Copyleft. At the time calc was placed under the GNU Lesser General Public License, a number of systems and distributions distributed calc without a Copyleft.
