To create this executable I have used some source-code from the public domain.
- The database functionality is from the SQLite amalgamation package from www.sqlite.org
- The SQLite extensions were likewise from www.sqlite.com
- The underlying regexp machine is based on the pcre2 C source files from https://www.pcre.org/
- Code snippets from the Q&A site https://stackoverflow.com/
- Ideas from the Microsoft Web site, and their SDKs
A special acknowledgement must be to my wife who has tolerated me developing this executable from its early days back in 1987.
