for many reasons, I think supporting *only* wrappers (or stuff written
specifically for bzr) is a better idea generally.  It's pretty cheap to
do anyway (if you want to wrap a system command, write a 6-line shell
script (counting the hashbang).

%cat >$BZRPATH/rules
#!/bin/sh
case "$1" in
    "--bzr-usage") ;;
    "--bzr-help") echo "more optimism" ;;
    *) bzr rocks ;;
esac
^D
%chmod +x $BZRPATH/rules
%bzr help rules
%bzr rules

'nuff said :-)

On the other hand, accepting arbitrary stuff may give people the false
impression that they should just symlink their favorite stuff into
bzrpath and then bend bzr around the way stuff prefers to be called.

best,
