Free/Libre Sqlite database management tool written in Delphi

I'm about to start working with Sqlite database engine in Delphi and I'm looking for free/libre database management tool to use for the API learning and for direct purpose - managing database(s). It has to be full of Sqlite-related features for the both purposes and, last but not least, it has to be published under free/libre license.

Important: to comply with Stackoverflow rules and avoid spamvertising answers I have to rule out anything good with Delphi source but without open source license. Sorry about that!
