The new address for the Phys documentation is:

The LHCb software is structured as a set of CMT projects. The Lbcom components project groups together packages shared by Boole and one or more other data processing applications (Brunel, DaVinci, Panoramix etc.). The Lbcom project depends on the LHCbSys project.

Packages belonging to Lbcom must follow certain rules for their external dependencies. The current list of Lbcom packages is here.

Reference documentation:
Documentation relating to each release of Lbcom is obtained by following the links in the table below. Here you can access directly the doxygen documentation of the most recent release, and the complete set of release notes.

Available versions
Normally, end users should not need to worry about selecting a version of Lbcom, as this is selected automatically when selecting an application version. When working outside an application, the environment can be set using the LbcomEnv script. The following versions are available in the release area

Reporting bugs
You can report bugs or view bug histories via the LHCb core software Savannah portal.

Supported platforms and compilers
Source code and binaries for supported platforms are available on disk (in AFS directory /afs/cern.ch/lhcb/software/releases - $LHCBRELEASES), and in the form of tar file distribution kits. The following platform+compiler combinations are supported:

Note that the binaries are built using sse2 extensions. They will not work on older machines that do not support the sse2 instruction set (e.g. Pentium III, AMD Sempron)
