The cldump utility allows you to extract the content of a Clarion database; Clarion is a Windows IDE similar to Delphi and others, and has its own (simple) database format.
I never used Clarion myself, but had to extract the data contained in such a database, so I Googled around and eventually found a couple of Technical Bulletins from Clarion, roughly describing the database format.
Although those bulletins are by no mean a complete documentation of the database format and contain errors and omissions, they were a good starting point to get cldump to the point where I could dump the databases I had to dump.
cldump can export the content of the database to CSV or SQL, plus its own "format". This format dumps all the meta data along with the data contained in the database. When using the SQL output, you'll get a nearly ready-to-go dump of the database that will create the table and the indexes and insert the data into the table. You'll need to hand-edit the dump to add the primary key and tweak the table definition a little to suit your needs or desires.
cldump uses only standard C functions, and works on both big and little endian machines.
The tarball contains the sources, a manpage and the technical bulletins I found on the web.
