This directory contains a network-based installer and packages for TeX Live. It is mirrored throughout CTAN.
The TeX Live web pages describe other ways to acquire the distribution, quick installation after obtaining it, documentation, and more.
If you have a complete copy of this directory, including the archive/ and tlpkg/ subdirectories, you can run the unpacked install-tl (install-tl.bat for Windows) script present here.
The update-tlmgr-latest.sh and .exe archives here are a way to recover from tlmgr being completely broken.
As an alternative to this network install, you can use the giant ISO image of the distribution.
Bug reports are welcome. Please email tex-live@tug.org with any problems, questions, suggestions. The tex-live mailing list archives may be of some use.
