How to configure restricted SSH ?

Dear list,

I want to restrict the SSH users to their home directory only and with a predefined
commands to be executed by them. A jailshell configuration might not be my exact requirement.
I like users to browse within his home and execute the command which I like to provide and
exclude/include in future. Say gzip is available for now but bzip2 might be given in future
and gzip will be excluded.  Is there any such setup through openssh ?

Thanks
