Description of merge algorithms

[Russ Brown]

I'm just evaluating bazaar and while trialling a scenario I encountered 
a criss-cross merge and was told to try --weave. But recently on this 
list I saw mention of --lca being a quicker and giving better results 
for this purpose.

I've not been able to find any docs that describe each algorithm with 
guidance on when each should be used. Could someone point me at some?

Also, if lca is better than for dealing with a criss-cross merge, should 
merge not recommend that instead instead of weave?

Thanks.
