Updating the srs.db
-------------------

The srs.db can be updated from the EPSG codes in the
GDAL installation:

1) Install latest GDAL, be sure to configure with --with-python.
2) Set PATH and PYTHONDIR if installed GDAL in non-standard location.
3) Run 'scripts/qgis_srs.sh > new_srs.sql'. It may take a minute or two.
4) Run 'sqlite3 new_srs.db < new_srs.sql'.'
4) Run 'sqlite3 new_srs.db <postprocess_srs.sql'

You can use sqlite3 to dump the contents from both srs.db and new_srs.db
before you decide to commit.
