.. _acknowledgments: Acknowledgment ============== QPDF was originally created in 2001 and modified periodically between 2001 and 2005 during my employment at `Apex CoVantage `__. Upon my departure from Apex, the company graciously allowed me to take ownership of the software and continue maintaining it as an open source project, a decision for which I am very grateful. I have made considerable enhancements to it since that time. I feel fortunate to have worked for people who would make such a decision. This work would not have been possible without their support.
