=head1 DESCRIPTION
|
||||
|
||||
You can use this module for accessing a note database. There are currently
|
||||
two versions of this module, one version for a SQL database and one for a
|
||||
binary file (note's own database-format).
|
||||
However, both versions provides identical interfaces, which means, you do
|
||||
not need to change your code, if you want to switch to another database format.
|
||||
|
||||
Currently, NOTEDB module is only used by note itself. But feel free to use it
|
||||
within your own project! Perhaps someone want to implement a webinterface to
|
||||
note...
|
||||
|
||||
=head1 USAGE
|
||||
|
||||
please see the section SYNOPSIS, it says it all.
