The biber executables we include in TeX Live are created by the biber
maintainers and third-party builders. They essentially bundle up the
many modules which biber requires, using the Par::Packer mechanism.
This process is described in the biber documentation. It isn't feasible
to incorporate it in the standard TL build.
Nevertheless, we want the result of TL's "make install" to be the full
bindir contents. So, we commit here the pre-made binaries for the
platforms for which they are available. The ones made by the biber
maintainers come through CTAN and our ctan2tl installs them; the ones
made by other folks we manually here. In any case, our make merely
checks if an executable is present here in the source directory for the
current platform, and if so, installs it.
The complication is hidden in the phrase "current platform". TL has its
own ideas about platform names, and the mapping from config.guess output
to TL platform name is not trivial. Therefore, we copy the standard
TeXLive/TLUtils.pm file here, along with a custom ./TeXLive/TLConfig.pm,
to avoid duplicating the platform-detection logic.
TLUtils.pm is kept in sync via the "srclist-update" mechanism; see
Master/tlpkg/dev/srclist.txt. The copy here in biber is a strictly a slave.
