We use a wrapper for /usr/bin/man.  If MANPATH is not set (the
default), it will be initialised to `echo $PATH | sed s/bin/man/g`
before invoking /usr/bin/man.This works very well.

=====================================

If your system default shell is sh or ksh,
1. Put PATH=/usr/bin:/usr/local/bin:...... and MANPATH=/usr/share/man:......
in your /etc/profile.
2. Put PATH=$PATH in /etc/skel/.profile (create this file). Ask all existing
sh and ksh users to change their PATH in .profile to PATH=$PATH.
If your system default shell is csh,
1. Put set path=(/usr/bin /usr/local/bin ...... ) and setenv MANPATH
"/usr/share/man:/usr/local/man:......" in your /etc/.login.
2. Put PATH=$PATH in /etc/skel/.login (create this file). Ask all existing
csh users to change their path in .login to set path=$path.

bash documents this in its PROMPTING section.  For this
particular prompt you would set:  PS1='\u@\H, \w % '
In ksh you could set something like:
  PS1="${LOGNAME:-$USER}@$(hostname)"', $PWD % '(This also works with bash.)


setenv host `hostname`
alias cd 'cd \!*; set prompt="$USER@$host `echo $cwd` % "'

See the tcsh man-page, thesection on Special shell variables, the item
'prompt'.
Example:
set prompt="$HOST\:%~% "
in your .tcshrc will automatically adjust the prompt to echo
current host and directory. No alias needed.
