Is vim-cmd supported on ESXi 5.x

While the commands are part of ESXi, there is no VMware documention that explains the commands.  Even worse, the vsphere management assistent (vma) is unaware of these commands.

vi-admin@vMA_1:~> vim-cmd --config ./bin/vMA_CLI.cfg -help
-bash: vim-cmd: command not found
vi-admin@vMA_1:~> esxcli --config ./bin/vMA_CLI.cfg -help
Usage: esxcli [options] {namespace}+ {cmd} [cmd options]

What is the status of the vim-cmd?

Thanks.
