Allows automatic unminification by the browser.
A postprocessing is required to:
- fix the paths to the sources;
- add the link from the minified script to its map.
If someone knows how to do the first item in Python or nodejs, please provide a
patch. A simple shell script is:
```
\#!/bin/sh
pwd=`pwd`
sed -i "s!$pwd/build!olsource!g" 'build/ol.js.map'
sed -i "s!$pwd!olsource!g" 'build/ol.js.map'
```
The second item should always be manually handled to avoid 404 errors
in debuggers
`echo '//# sourceMappingURL=ol.js.map' >> build/ol.js`
Finally, create an alias / copy ol3 directory to /olsource in your
deployed environment.
