Currently a docset is constructed in the current working directory. You can specify the source directory with a -s (or --source) flag, but not the destination.
Proposed: -d
(or --dest ) directory. Recursively create directory path to location if it does not exist.
Should be relatively straight-forward to add the switch to the 'build' command and then concatenating it with the docset dirname when calling the os.MkdirAll
