Well,
I see you two are up to it and will probably do a better job than me. I 
tried to use gs as pdftk. It works but it is pretty slow. As I launch gs 
for each page separately it reads the whole file for each page 
extraction which gives a time to split the document which is ... 
quadratic in the number of pages !

  I suppose you can launch just gs once and do a series of commands to 
avoid this issue but I haven't found yet how. I also suppose Stefan will 
use the function doc-view-pdf->png-1 for each page when doing the lazy 
reconversion which will also call gs once for each page ... if I find a 
workaround I will share it !

Anyway lazy reconversion is ok for me, and I am happy to have been 
useful at least  for counting as one among others :)

Thanks to both of you !

Carlos
