Some folks might think: “you still use RCS”?!? And we will say, hey, at least we switched from SCCS to RCS back in … I think it was around 1994 ... at least we are keeping up! :-) :-) :-) Logs say that SCCS version 18 became RCS version 19 on 1994 March 18. RCS served us well. But now it is time to move on. And so we are switching to git. Calc releases produce a lot of file changes. In the 125 releases of calc since 1996, when I started managing calc releases, there have been 15473 file mods!

Calc's relationship to the GNU Lesser General Public License
|
|
------------------------------------------------------------
|
|
|
|
In section 0 of the GNU Lesser General Public License, one finds
|
|
the following definition:
|
|
|
|
The "Library", below, refers to any such software library or
|
|
work which has been distributed under these terms.
|
|
|
|
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.

Why calc did not use the GNU General Public License
|
|
---------------------------------------------------
|
|
|
|
It has been suggested that one should consider using the GNU General
|
|
Public License instead of the GNU Lesser General Public License:
|
|
|
|
http://www.gnu.org/philosophy/why-not-lgpl.html
|
|
|
|
As you can read in the above URL, there are times where a library
|
|
cannot give free software any particular advantage. 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.
