This repository has the code drop from tut 2008-11-30 (they use dates as versions) in the 'vendor' branch, with Linden Lab changes applied in the 'default' branch.
The sources are all in the directory 'tut'; when unpacked from the tut distribution that directory was 'tut-2008-11-30' but has been renamed. That version identifier was moved into the 'build-cmd.sh' script as part of the new convention for handling version numbers (creating a version_file rather than hard coding it). See comments in build-cmd.sh
To add an updated drop from the tut project, switch to the vendor branch: hg up vendor
copy the new drop onto the by renaming the top level directory from the distribution. Then:
hg addremove hg commit hg up default hg merge vendor
