probably won't be helpful in your case, but less has several useful
environment variables.  the less man page has a very useful explaination
of the LESSOPEN environment var.  it's quite possible to configure less
to page through a lot of things in a handy way.  my lessopen script
works like so:

    LESSOPEN="|~/bin/lessopen.sh %s"

    #! /bin/sh
    case "$1" in
	*.tar)
	    tar tvf "$1"  2>/dev/null
	    ;;
	*.tar.gz)
	    tar ztvf "$1"  2>/dev/null
	    ;;
	*.Z|*.gz)
	    zcat "$1"  2>/dev/null
	    ;;
	*.bz2)
	    bzcat "$1"  2>/dev/null
	    ;;
	*.rpm)
	    rpm -qilp "$1"  2>/dev/null
	    ;;
    esac

essentially, less is like the emacs of pagers.
