Now start script, generated by vws uses shel line continuation chardtecr to collect lots of options into single command line.

This doesn't allow to put shell comments in, neither comment out some options to disable them temporarily.

Maxim Nikuiln suggested use of bash arrays instead of continuation. Something like

ARG[1]="-name name"
ARG[2]="-net user"
ARG[3]="-mem 4G"
