Just discovered the following in need for an 8.15.x basekit, without wanting to install this release:
- Download the desired Installer from http://downloads.activestate.com/ActiveTcl/releases/
- sdx mksplit installername gives 2 Files, one named ...head and one named ...tail
- (the head itself seems to be a spezialized tclkit, but it's complaining about the missing tail...;-)
- sdx unwrap tail
The wanted basekits are now below the created VFS-structure under payload/bin.
