The Computational Geometry Algorithms Library (CGAL) is a C++ library that
aims to provide easy access to efficient and reliable algorithms in
computational geometry.

CGAL Releases
=============
The primary vector of distribution of CGAL are source tarballs, released
twice a year, announced on [the web site of CGAL](https://www.cgal.org/).

Getting Started with CGAL
=========================

**Since version 5.0, CGAL is a header-only library, meaning that
it is no longer needed to build CGAL libraries before it can be used.**

Head over to the [CGAL manual](https://doc.cgal.org/latest/Manual/general_intro.html)
for usage guides and tutorials that will get you started smoothly.

License
=======
See the file [LICENSE.md](LICENSE.md).

CGAL Git Repository Layout
==========================

The Git repository of CGAL has a different layout from release tarballs. It
contains a `CMakeLists.txt` file that serves as anchor for configuring and building programs,
and a set of subfolders, so called *packages*. Most packages
implement a data structure or an algorithm for CGAL (e.g., `Convex_hull_2`,
or `Triangulation_3`); however some packages serve special needs:

* `Installation` - meta-files and CMake-support
* `Maintenance` - infrastructural support
* `Core`, `CGALimageIO`, `Qt_widget`, `GraphicsView` - component libraries
* `Scripts` - scripts to simplify developer's and user's work
* `Testsuite` - infrastructure for testsuite
* `Documentation` - infrastructure for CGAL's manual
* `STL_Extension` - extensions to the standard template library
