how "more" and "less" work together?

[s m]

hello all

i have freebsd9.2 and want to customize "more" functionality but i can not
find any code for it; therefore i change the "less" code.

now my question is how more and less work together?? i compiled my code and
if i run less (which i change it) manually, it works fine, but more command
doesn't use it. i put my less daemon is /usr/bin.

any body knows how can i apply my changes to more command? how can i update
more daemon (which is located in /usr/bin) in order to use the new less
daemon?

thanks in advance,
SAM
