The macports.sqlext is meant to ease debugging the registry database by
providing the necessary SQLite extensions to examine and modify the database
using the sqlite3 command line tool.

To use this SQLite extension, use '.load macports.sqlext' at the sqlite3 prompt
right after attaching the registry.db file.

Example:

$ sqlite3 /opt/local/var/macports/registry/registry.db
...
sqlite> .load /Users/julesverne/src/macports/trunk/base/src/cregistry/macports.sqlext
