How to make custom library in Simulink available to other users and in different versions?

I wonder if there is a way to import a custom library. I wouldnt want to re-create for all users the custom library. Or one should create a custom Toolbox to have/use a set of custom re-occuring functions and blocks?

If you have a newer version of MATLAB (e.g. R24b), you can save/export a Simulink model or library as older version (e.g. R23b), then other users can use it, assuming there are no incompatibility issues in the model contents.
