Overview
--------

BRL-CAD consists primarily of libraries, applications, scripts,
documentation, geometric models, images, and build infrastructure.
The BRL-CAD libraries include the headers in the include/ directory as
well as all of the directories that begin with the prefix "lib" in the
src/ directory (e.g. src/librt/).  All of BRL-CAD's libraries are
covered by the terms of the GNU Lesser General Public License (LGPL)
as published by the Free Software Foundation unless noted otherwise in
the source files.

Most of BRL-CAD's build infrastructure (i.e. files required by the GNU
Build System such as the configure.ac and all Makefile.am files), a
variety of scripts located in the misc/ and sh/ directories, and the
testing infrastructure (scripts and resources) are provided either
under the BSD license or are in the public domain.  Refer to each
individual file for specific terms.

BRL-CAD's documentation consists of manual pages located throughout
the package, most of the files in the doc/ directory, and the
top-level administrative project text files (e.g. README & AUTHORS).
Unless otherwise denoted, all of BRL-CAD's documentation is made
available under the terms of the GNU Free Documentation License (GFDL)
or, at your option, under the terms of the GNU General Public License
(GPL) as published by the Free Software Foundation.  Several older
documents (e.g. published by the U.S. Government prior to being
released as Open Source) are in the public domain.  Refer to each
document and the original author(s) individually for specific terms.

Unless previously described or otherwise already covered by another
license, the BRL-CAD package is covered under the terms of the GNU
General Public License (GPL) as published by the Free Software
Foundation.  This includes but is not limited to the applications,
geometric models, images, and other resource data included in the
BRL-CAD distribution.

The full text of the GPL, LGPL, GFDL, and BSD license should be
included in the source distribution of BRL-CAD in the doc/legal/
