Hyunsik Choi commented on TAJO-912:
-----------------------------------

Ok, I accept your proposal. Your claim is reasonable.

In addition, could you add one member variable to contain the target document 
version that HelpCommand instance will use? It will avoid repeated delay or 
hanging which may occur in some network environments.

After we discuss the workflow change, I'll update the wiki page or website. 
Thanks!
