Log:
* Added script for updating the srs.db from the GDAL installation (thanks msieczka !)
* Added a small README on the process on how to do the above
* Change the CRS recognition when reading from projects, so it tries to match the proj4 string if valid. This is a must when the srs.db now is updated
* Changed to read ellipsoid an projection acronyms from srs.db nistead of qgis.db (mostly)
* Misc. clean up of comments and deletion of stale code.
* Fixes #1534.

+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.

+# AUTHOR:       Maciej Sieczka, msieczka at sieczka.org, http://www.sieczka.org
+#
+# PURPOSE:      Create a QGIS srs.db-compliant SQL script with SRS, ellipsoid
+#               and projections defs based on the output of installed PROJ.4 and
+#               GDAL.
+#
+# VERSION:      1.1.0, 2009.03.19
+#
+# COPYRIGHT:    (c) 2008,2009 Maciej Sieczka
+#
+# LICENSE:      This program is free software under the GNU General Public
+#               License (>=v2).
+
+# CHANGELOG:
+#
+# 1.1.0:
+# - Reorganize the code into functions.
+# - Support qgis.db convenient update too.
+# - Workaround the issue http://trac.osgeo.org/gdal/ticket/2900.
+#
+# 1.0.3: Minor cosmetics in comments.
+#
+# 1.0.2: Replace 'latlon' and 'lonlat' in the `proj -le` output, so that QGIS
+#        can parse the 'tbl_projection' table to provide the GCSs list in the
+#        'Projection' dialog (BTW, the dialog should be called 'Coordinate
+#        system' actually, as a projection is only a component of a cs).
+#        More comments.
+#
+# 1.0.1: Typos in comments fixed.
+#
+# 1.0:   First public release.
+
+# USAGE:  1. qgis_srs.sh --full/--tmpl > output.sql
+#         2. import output.sql into SQLite Database Browser
+#         3. save as a new dbase, name it srs.db (--full) or qgis.db (--tmpl),
+#            use with QGIS
+
+# DETAILS:
+#
+# The script creates an SQL plain text dump that can be imported into
+# SQlite db eg. using SQLite Database Browser's "Import > Database from
+# SQL file" tool.
+#
+# The ellipsoids (tbl_ellipsoid) and projections (tbl_projection) tables
+# are created parsing the proj command output. I chose this approach,
+# because looking at the original tables content it seems the original
+# tables were created the same way.
+#
+# The tbl_srs table is created parsing the epsg_tr.py output. EPSG codes
+# to process are taken from the installed GDAL's pcs.csv and gcs.csv files.
+#
+# Tables structure and final SQL statements creating the view and indices
+# were copied from the original srs.db shipped with QGIS trunk r8544,
+# after dumping it to a plain text format with SQLite Database Browser.
