+<h1>About<a class="headerlink" href="#about" title="Permalink to this headline">¶</a></h1>
+<p>PROJ is a generic coordinate transformation software that transforms geospatial
+coordinates from one coordinate reference system (CRS) to another. This
+includes cartographic projections as well as geodetic transformations. PROJ
+is released under the <a class="reference internal" href="#license"><span class="std std-ref">X/MIT open source license</span></a></p>
+<p>PROJ includes <a class="reference internal" href="apps/index.html#apps"><span class="std std-ref">command line applications</span></a> for easy conversion of
+coordinates from text files or directly from user input. In addition to the
+command line utilities PROJ also exposes an
+<a class="reference internal" href="development/reference/index.html#reference"><span class="std std-ref">application programming interface</span></a>, or API in short. The API
+lets developers use the functionality of PROJ in their own software without having
+to implement similar functionality themselves.</p>
+<p>PROJ started purely as a cartography application letting users convert geodetic
+coordinates into projected coordinates using a number of different cartographic
+projections. Over the years, as the need has become apparent, support for datum
+shifts has slowly worked its way into PROJ as well. Today PROJ supports more
+than a hundred different map projections and can transform coordinates between
+datums using all but the most obscure geodetic techniques.</p>

+<p>PROJ uses the MIT license. The software was initially released by the USGS in
+the public domain. When Frank Warmerdam took over the development of PROJ it
+was moved under the MIT license. The full text of the license follows, and can
+also be found in the file <code class="docutils literal notranslate"><span class="pre">COPYING</span></code>, at the top level of the source
+distribution package.</p>
+<div class="highlight-none notranslate"><div class="highlight"><pre><span></span>
+All source, data files and other contents of the PROJ package are
+available under the following terms. Note that the PROJ 4.3 and earlier
+was &quot;public domain&quot; as is common with US government work, but apparently
+this is not a well defined legal term in many countries. Frank Warmerdam placed
+everything under the following MIT style license because he believed it is
+effectively the same as public domain, allowing anyone to use the code as
+they wish, including making proprietary derivatives.
+
+Initial PROJ 4.3 public domain code was put as Frank Warmerdam as copyright
+holder, but he didn&#39;t mean to imply he did the work. Essentially all work was
+done by Gerald Evenden.
