jextract to write classifies if a directory is specified with -o

[Henry Jen]

I will add -d.

We didn’t use -jar because historically, we are generate source files and not jar files. -o for output file is general convention and is what most C compilers has. We can add —jar as long option.

I don’t like -f, it’s neutral on input and output, reasonable choice for tools like jar, but probably not here.

Cheers,
Henry

I'd probably see it more as a post-processing step which, after placing your classfiles in the -d folder, it would also generate a jarfile where you want it to be (to mimic how users typically do it by piping multiple shell commands).
