It is maintained (at least to some extent) at
https://github.com/OlivierJG/botansqlite3 and contains several fixes
which are not included in this version.

-Build instructions for BotanSqlite3
----
-
-Requirements:
-  1. Botan 1.9.0 or later
-  2. SQLite3 amalgamation source, version 3.7.12.1 or later (previous versions may work, some will need minor changes)
-
-
-Building:
-
-1. Extract sqlite3 amalgamation to a directory and add BotanSqlite3 source files
-
-   If desired, codec.h can be modified to tweak the encryption algothrithms and parameters. (Defaults to Twofish/XTS with 256 bit key)
-
-2. Apply the patch "sqlite3.diff":
-    $ patch -p0 < sqlite3-amalgamation.patch
-
-   If the patching fails for some reason (ie, changes in SQLite3), it should be trivial to do it manually.
-
-3. Compile the sqlite3 library with Botan encryption support:
-    $ gcc -c sqlite3.c -o botansqlite3.o && gcc -c codec.cpp -o codec.o `pkg-config --cflags botan-1.10` && ar rcs libbotansqlite3.a botansqlite3.o codec.o
-    
-    (replace "botan-1.10" with appropriate version)
-
-Testing:
-
-1. Build the test:
-      $ g++ test_sqlite.cpp -o test_sqlite `botan-config-1.10 --libs` ./libbotansqlite3.a
-      
-      (replace botan-config-1.10 w/ appropriate version)
-
-2. Run the test
-      $ ./test_sqlite
-
-3. Look for "All seems good"
