OPL - Oveas Perl and PHP Library

version 2.1.0

Overview

Documentation

OPL documentation is currently work in progress. If you only need it for use with another Oveas script, the README provides you with all installation and configuration instructions, all other required information is in the documentation of the script that uses OPL.

Developing with OPL

Since documentation is not yet ready for release, it might be difficult to develop your own applications using OPL. If you do have any questions however, please use the OPL Forum. All input from there will be part of the documtation once released.

Commercial Support

OPL2 came with a new feature; only one installation of OPL and all applications was required for multiple (virtual) servers.
In version 2.1.0, this Virtual Server Support has been removed from the freeware release. This support is still available however, but installations are site specific and will be prepared on request.
