This should have worked, but for some reason it does not:

context --jobname=shadow main.tex

The output says:

system          > files > jobname 'shadow', input './main', result 'shadow'
.....
mkiv lua stats  > result saved in file: shadow.pdf, compresslevel 3, 
objectcompresslevel 3

but no shadow.pdf file is created.
