Tax form (Steiererklärung) under Linux
In Luxemburg, the tax-form (Steiererklärung) can be made electronically. For that, the ministery gives a form  that is an interactive pdf. Calculation of different areas is done automatically. Therefore, the user must use Adobe Reader for this, otherway, editing and automatic calculation isn't done. Unfortunately, many Linux Distries provide no longer the Adobe Reader, because Adobe stopped its developpment for Linux. An old version (9.5.4) is available on Adobe's website  where the calculation works, but not all dependencies match. I tried different Alternatives under Linux (kpdf, PDF Studio, ...) but none can do the calculation. Are there alternatives that can do the interactive calculation?
