I hunt bug !

But the name bug for the checkout was not a good example...

I've somes project that i use in others projects (somes libraries), 
i keep one branch for each version and i actualy checkout inside the 
target projects to collect them.


projectX/extlib/mylib (co from mylib)
        /lib/mylib --> ../extlib/mylib/lib
Then i had this idea to create the checkout in the same repository as 
the original library project and make a symlink of this checkout in the 
target project.
Like that i gain place, i can see in the repository how much project use 
this libraries and i can symlink only a part of the tree.

    /mylibforX (co from mylib)
    /mylibforY (co from mylib)

projectX/lib/mylib --> /repo/mylibforX/lib

of course i can use branch for this, but i thought that checkout was 
more explicit...
