Colored manpages with tcsh?

Question

I really like the colored manpages which can are achieved by

export LESS_TERMCAP_mb=$'\E[01;31m'
export LESS_TERMCAP_md=$'\E[01;31m'
export LESS_TERMCAP_me=$'\E[0m'
export LESS_TERMCAP_se=$'\E[0m'
export LESS_TERMCAP_so=$'\E[01;44;33m'
export LESS_TERMCAP_ue=$'\E[0m'
export LESS_TERMCAP_us=$'\E[01;32m'

in your .bashrc or .zshrc. My question is: How do I export these variables in tcsh? I have to use tcsh at work and cannot get it working. I tried plenty of variations, but nothing worked. Simply replacing export with setenv and = with " " doesn't do the trick. But it should work somehow. If i start a tcsh out of my zsh with this exports set I can enjoy colored manpages in tcsh, also. But that's an ugly workaround.
