Special Build of OpenLayers
---------------------------

At the time the project was conceived, a newer version of OpenLayers was needed
than the latest release, for some features and bug fixes.

Subversion checks out trunk from OpenLayers, at a given revision.

Then, a compressed version of OpenLayers was created from the check out.

To upgrade to a newer version from source repository, update all external references
to the desired revision. Then, run python script to generate new compressed version.
Finally, test and commit changes.

> cd <dir>  (directory where readme.txt is located
> svn propedit svn:externals .
> svn up
> cd build
> ./build.py
> rm ../OpenLayers.js
> mv OpenLayers.js ../.
> cd ..
(test)
> svn ci



Debug build of OpenLayers
-------------------------

To debug OpenLayers, one need to include all the OpenLayers files in the parent
HTML file and drop the use of the compressed version of OpenLayers.

OpenLayers has a large set of files, and to include them all in the proper
order can be daunting. The script "all_libs.sh" generates the script statements
required for the parent HTML page.
