Hi, it may be a bit early, but does anybody mind when I add this rule: InstallBin /boot/beos/preferences : $(<) ; to the Preference rule? It would allow to invoke "jam install" and to have the executable put into the correct directory - the downside would be that you can overwrite your original preferences applications relatively easy. At least for the Workspaces preferences app, this would be very handy (as this is complete :-)). But I can also add this rule only for that application or in my local copy only. Adios... Axel.
