Currently what I have in my script that I've been applying suggestions
to, I have:
case "$pagefile" in
*.bz2)
exec bzcat "$pagefile" | "$PAGER" ;;
*.gz)
exec zcat "$pagefile" | "$PAGER" ;;
*)
exec "$PAGER" "$pagefile" ;;
esac
Though I don't understand this line:
> "$CAT" "$pagefile" | "$PAGER" "$pagefile"
Shouldn't that be?:
"$CAT" "$pagefile" | "$PAGER"

The other thing I wanted to mention was the possibility of extending
this little man script, or creating an alternate, so that it could look
up man pages from a single file to prevent a whole 1kb, 2kb, 4kb or w/e
sized inode from being used to hold a single 200 byte compressed ascii
man page. Does this sound like a good idea?
