| 37 | * Handwritten code to wrap version 3.x of the Berkeley DB library, |
Barry Warsaw | 9a0d779 | 2002-12-30 20:53:52 +0000 | [diff] [blame] | 38 | * written to replace a SWIG-generated file. It has since been updated |
Gregory P. Smith | 41631e8 | 2003-09-21 00:08:14 +0000 | [diff] [blame] | 39 | * to compile with BerkeleyDB versions 3.2 through 4.2. |
Martin v. Löwis | 6aa4a1f | 2002-11-19 08:09:52 +0000 | [diff] [blame] | 40 | * |
| 41 | * This module was started by Andrew Kuchling to remove the dependency |
| 42 | * on SWIG in a package by Gregory P. Smith <greg@electricrain.com> who |
| 43 | * based his work on a similar package by Robin Dunn <robin@alldunn.com> |
| 44 | * which wrapped Berkeley DB 2.7.x. |
| 45 | * |
Barry Warsaw | 9a0d779 | 2002-12-30 20:53:52 +0000 | [diff] [blame] | 46 | * Development of this module then returned full circle back to Robin Dunn |
| 47 | * who worked on behalf of Digital Creations to complete the wrapping of |
| 48 | * the DB 3.x API and to build a solid unit test suite. Robin has |
| 49 | * since gone onto other projects (wxPython). |
| 50 | * |
| 51 | * Gregory P. Smith <greg@electricrain.com> is once again the maintainer. |
| 52 | * |
| 53 | * Use the pybsddb-users@lists.sf.net mailing list for all questions. |

| 55 | * file is shared with the PyBSDDB project at SourceForge: |
| 56 | * |
| 57 | * http://pybsddb.sf.net |
| 58 | * |
