tlmgr (TeX Live Manager) is the package manager for the TeX Live distribution, handling installation, updates, and removal of LaTeX packages and fonts. It automatically resolves dependencies when installing new packages and can update the entire distribution with update --all.
The tool provides search and information commands to explore the thousands of available packages by name or description. Packages can be backed up before changes and restored if an update causes problems. The --self flag updates tlmgr itself separately from other packages.
Running tlmgr requires a native TeX Live installation rather than a distribution-packaged version, as Linux distribution packages typically manage TeX packages through their own package manager instead.
