69 DBI::DBD::SqlEngine abstracts the usage of SQL engines from the DBD.
70 DBD authors can concentrate on the data retrieval they want to provide.
71
72 It is strongly recommended that you read DBD::File::Developers and
73 DBD::File::Roadmap, because many of the DBD::File API is provided by
74 DBI::DBD::SqlEngine.
75
76 Currently the API of DBI::DBD::SqlEngine is experimental and will
77 likely change in the near future to provide the table meta data basics
78 like DBD::File.

107 Where can I go for more help?
108 For questions about installation or usage, please ask on the
109 dbi-dev@perl.org mailing list.
110
111 If you have a bug report, patch or suggestion, please open a new report
112 ticket on CPAN, if there is not already one for the issue you want to
113 report. Of course, you can mail any of the module maintainers, but it
114 is less likely to be missed if it is reported on RT.
115
116 Report tickets should contain a detailed description of the bug or
117 enhancement request you want to report and at least an easy way to
118 verify/reproduce the issue and any supplied fix. Patches are always
119 welcome, too.
