 Instructions for importing a new release of SQLite from sqlite.org.
 
-Note: our current base version is 3.6.18.
+Note: our current base version is 3.7.6.3.
 
 First, you need to be on Linux.
 
 # Determine the versions of the release you want and the release we currently
 # have. (See the VERSION file to determine which release we currently have.)
 # You may wish to consult http://www.sqlite.org/changes.html to find out what
 # changes have been made in each release.
 # Note - this is just an example. Always refer to the version above for our
 # real current version.
 # Set some variables to remember the versions, e.g.:
-BASE=3.6.18
-LATEST=3.6.22
+BASE=3.7.6.3
+LATEST=3.7.6.4
 
 # Get to the src/third_party directory in your Chromium client:
 cd src/third_party
 
 # Download the .tar.gz files for the releases:
 # (If the URL changes you might need to find the new one.)
+# TODO(shess): Rewrite this to track the new naming format.  Meanwhile,
+# manually navigate to www.sqlite.org and find downloads, use "legacy" version.
 wget http://www.sqlite.org/sqlite-$BASE.tar.gz
 wget http://www.sqlite.org/sqlite-$LATEST.tar.gz
 
 # Extract the vanilla current and desired versions:
 tar xzf sqlite-$BASE.tar.gz
 tar xzf sqlite-$LATEST.tar.gz
 
 # Use kdiff3 to merge the changes:
 kdiff3 -m sqlite-$BASE sqlite-$LATEST sqlite

    WebKit/WebCore/platform/sql/chromium/SQLiteFileSystemChromiumPosix.cpp
    to correctly implement the "unused file descriptors" logic in the
    xDlOpen() method. The new functions are
    chromium_sqlite3_get_reusable_file_handle(),
    chromium_sqlite3_update_reusable_file_handle() and
    chromium_sqlite3_destroy_reusable_file_handle(). Also, added the
    chromium_sqlite3_fill_in_unix_sqlite3_file() function that calls
    fillInUnixFile(), which will be made static again as soon as a
    WebKit patch using the new function lands.
