What is deal.II?
================

deal.II is a C++ program library targeted at the computational solution
of partial differential equations using adaptive finite elements. It uses
state-of-the-art programming techniques to offer you a modern interface
to the complex data structures and algorithms required.

For the impatient:
------------------

Let's say you've unpacked the .tar.gz file into a directory /path/to/dealii/sources.
Then configure, compile, and install the deal.II library with:

    $ mkdir build
    $ cd build
    $ cmake -DCMAKE_INSTALL_PREFIX=/path/where/dealii/should/be/installed/to /path/to/dealii/sources
    $ make install    (alternatively $ make -j<N> install)
    $ make test

To build from the repository, execute the following commands first:

    $ git clone https://github.com/dealii/dealii
    $ cd dealii

Then continue as before.

A detailed *ReadME* can be found at [./doc/readme.html](https://dealii.org/developer/readme.html),
[./doc/users/cmake_user.html](https://dealii.org/developer/users/cmake_user.html),
or at https://dealii.org/.

Getting started:
----------------

The tutorial steps are located under examples/ of the installation.
Information about the tutorial steps can be found at
[./doc/doxygen/tutorial/index.html](https://dealii.org/developer/doxygen/deal.II/Tutorial.html)
or at https://dealii.org/.

deal.II includes support for pretty-printing deal.II objects inside GDB.
See [`contrib/utilities/dotgdbinit.py`](contrib/utilities/dotgdbinit.py) or
the new documentation page (under 'information for users') for instructions
on how to set this up.

[Docker Hub](https://hub.docker.com/r/dealii/dealii). You can
use any of the available version
([list of available tags](https://hub.docker.com/r/dealii/dealii/tags))
by running, for example:

    $ docker run --rm -t -i dealii/dealii:master-focal

The above command would drop you into an isolated environment, in which you
will find the latest version of deal.II (master development branch) installed
under `/usr/local`.
