1. Add root for --all.
2. Use "$VIMRC" instead of setting IFS.
3. No need to "cd $1", but $1 must be an absolute path.
The command in "Install for multiple users" needed to be updated:
bash /opt/vim_runtime/install_awesome_parameterized.sh /opt/vim_runtime user0 user1 user2
bash /opt/vim_runtime/install_awesome_parameterized.sh /opt/vim_runtime --all
(Better use bash instead of sh, in consider of sh->dash in debian or ubuntu to avoid "Syntax error")
/opt/vim_runtime can be any directory, as long as all the users specified have read access, but must be an absolute path.
