If we need 4 cmmand to convert test.dvi to test.png 1. cmd1 test.dvi test.a 2. cmd2 test.a test.b 3. cmd4 test.b test.png
does it work correctly? can %b.a convert to text.a ?
("cmd1 %b.dvi %b.a"
"cmd2 %b.a %b.b"
"cmd3 %b.b %b.png")
if it works properly, i suggest merge org-compile-file feature first, i will
rebase my patch to it before merge.
