For more advanced usage a set of flags are provided.

Verbose--vfalsefalseDebug output into console
Strict--sfalsetrueStrict check of category types
All--allfalsefalseWhether to check all commits on given branch. Takes precedence over LIMIT flag

On top of that a single argument is allowed:

commitsar <from commit>...<to commit>

e.g. commitsar 7dbf3e7db93ae2e02902cae9d2f1de1b1e5c8c92...d0240d3ed34685d0a5329b185e120d3e8c205be4

If only one commit hash is used then commitsar will assume it to be the TO commit.
