Licence switch: from GPL to LGPL

As already mentioned, PHProjekt 6 is the result of a complete rebuild, rewritten from scratch. We used this chance to look for another Open Soucen Licence and after several discussions, we decided to put PHProjekt 6 under the LGPL. The LGPL is often called 'library GPL' and is recommended for software libraries. So What are the reasons to put a complete project management suite under the LGPL?

First of all, we have chosen an original and widely used licence model, thus avoiding any 'propietary, home brewed' OS licence.
By choosing a commonly known, easy to understand and liberal OS licence, we want to attract open source developers and invite them to contribute to the PHProjekt project.

Furthermore, each developer or company (including Mayflower itself) can develop own modules and or additional software, link it to PHProjekt 6 and put the module under another (even propietary) licence. We think that this also will raise the interest to the new version of PHProjekt. However, modifications on the core of PHProjekt 6 have to be open again. We hope, that improvements and patches will make their way back into the repository and can be released with the next versions.

By choosing the LGPL, we commit us to the freedom of software, and we respect the freedom to link software to PHProjekt 6 with a propietary licence.
