question about git-submodule

hi,

even after reading the manpage, i'm not sure about what git submodules are for :)

i mean, first i thought that after configuring a submodule under libfoo, then a git pull will update libfoo's repo under libfoo, too. or something like that. but in fact even after reasing the source, i'm not sure about what is git submodule update is for :s

sorry for the lame question :)

thanks,
