That command installs "most" and make this command as the default man reader. The "most" works like "less" (the current man reader), but it render colors for manpages and may do more things. Read "man most".

There are 7 alternatives - vote for the best!
Colourful with vim regex finding goodness!
Replace the 'man' with the page to be looked up.
I actually have as a function in my .profile

export MANPAGER=most
Sorry, going from less to most was just not intuitive. It does not retain the standard "vi" moving around / search features.
Alternately, if you set the LESS_TERMCAP series of variables to something like this...
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'
...and set LESS=-R (I personally recommend -iFRX, but only -R is germane here), less will colorize manpages.
