Once we pull down the full FreeSWITCH version using git, should we continue to use 'make current' to update thereafter?

I started with this command and interrupted it just after it had pulled the source changes. I was surprised to see that "fs_cli" no longer worked. I went to freeswitch/bin and fs_cli was gone. Are the contents of this directory removed in 'make current'?

I also saw core files (core.pid?) in the freeswitch/bin folder. Is it safe to remove these? They are about 200M each.

Thanks, Lars
