re-make Bamse to produce a 'mkInstaller' builder for your project.
Use --help to discover the set of options supported, but typical
invocations are:
foo$ mkInstaller --generate-guids -o myInstaller.msi c:/path/to/the/top/of/my/dist/tree
foo$ mkInstaller -u -o myInstaller.msi c:/path/to/the/top/of/my/dist/tree
The latter one re-uses the GUIDs of the existing 'myInstaller.msi'
to create a new one. You want to do that to when creating updates/bugfixes
of existing products without upgrading its version numbers; please notice
that it overwrites the .msi in the end, so please make a copy if the
MSI is precious..
