All I know is that when I try the suggested command line
Code:
/opt/calibre/ebook-convert "The Economist.recipe" Economist.mobi
or
Code:
/opt/calibre/ebook-convert "The Economist.recipe" Economist.epub
I generated an output file around 6 meg in size for either example. Note that
- I didn't need to run the code as root
- Calibre downloaded the current recipe for me.
