On Ubuntu:

[extdiff]
cmd.cxdiff = diff
opts.cxdiff = -Nprc5
cmd.meld =
cmd.cdiff = colordiff
opts.cdiff = -uprN
cmd.cwdiff = diff
opts.cwdiff = -wBNprc -C 5
cmd.kdiff = kdiff3
opts.kdiff =
cmd.xxdiff = xxdiff
opts.xxdiff =
cmd.sub = submerge
opts.sub = diff

I use hgtk. And I almost never using anything except meld from the above.
