[Boost-build] How to specify different install rules for different variants?

Hello,

I'm starting to use boost build and I have the following problem:

I have a Jamfile in which I specify one target like this:

        exe MyExe: [ glob ./Source/*.cpp ] ;

Now, I want to specify install rule for my target but I want install 
location to be different for different build variants. For example, when 
building debug variant I want location to be /bin/debug and for release 
variant /bin/release. The first idea was to add something like this into 
Jamfile:

        install bin/debug: MyExe: <variant>debug ;
        install bin/release: MyExe: <variant>release;

But this doesn't do things exactly as I would like to. If I want to 
build debug version with "bjam debug" command, because of the second 
install rule release variant is also built. I want to avoid that. So 
second solution I came up with was to parse command line arguments, like 
this:

        import modules ;
        local argv = [ modules.peek : ARGV ] ;

        if debug in $(argv)
        {
                     install bin/debug: MyExe: <variant>debug ;
        }
        if release in $(argv)
        {
                     install bin/release: MyExe: <variant>release;
        }

But this solution is not "clean" as I would like to. For example, if I 
want to build default variant with "bjam" command (with no debug/release 
parameters) I have to add more logic in the code above. I would like to 
avoid that because it is repetitive task I have to make for every project.

Does anybody know some better solution?
Many thanks in advance.
