9 Debugging

To get more insight into what’s going on when you upload a tarball, use the -v (--verbose) option. This option is incremental, that is the more times you supply it, the more verbosity you get as a result. The single -v option causes the program to verbosely annotate each step it is taking. Two -v options instruct it to additionally print the content of the produced directive files. Three options will additionally print a detailed protocol transcript.

Another option useful for debugging is --dry-run (-n). It instructs grayupload to do everything in verbose mode (single -v is implied), but not actually upload any files.
