Hello Jeremias, I'm not saying that this is simple, I'm just saying pre-conditions, when we would be able to continue invest our efforts into integration into FOP. You are absolutely right, saying that there should be interest of the public community to such a work. At present, we get first feedback/requests on our work after about 5 month of absolute silence. This basically means that there is no demand on this feature. Either peoples are using other solutions or they are simply want to have additional feature in a list which says MathML support without any real background for that. Moreover, what I've learned so far is that FOP is not trying to get publication ready PDF's (what is my case) rather then readable XML. Correct me, if I'm wrong.
The reasons for rare commits is that on our side there is more then one developer working on the project. While we do not have any feedback, we do not update public repository and just using our private one. There is another weak reason, why I cannot made release on sourceforge.net. I have only CVS commit rights to the JEuclid project and cannot make any releases. My perception is that we will continue making half-year commits to the sf.net repository with patched FOP and JEuclid which fully covers our needs. If somebody would be interested for somebody to integrate into FOP thunk, s/he is welcome. -- Best regards, Gennadiy mailto:[EMAIL PROTECTED] Wednesday, May 3, 2006, 3:13:11 PM, you wrote: JM> I forgot to CC the jeuclid list when I replied to Max.
