tlmgr-conf is a part of the TeX Live Manager (tlmgr) suite. It's specifically used to configure tlmgr itself, not TeX Live as a whole. This configuration includes setting the repository location (where tlmgr downloads packages from), adjusting network settings, and modifying other operational parameters.

You can set the repository URL to a local directory, a network mirror, or even a specific TeX Collection Network archive. Network settings are especially useful for computers behind proxies.

Changes made with tlmgr-conf affect the way tlmgr behaves globally for all users of the TeX Live installation. Therefore, administrative privileges are typically required to modify these settings.

Modifying configurations with tlmgr-conf can significantly impact your TeX Live installation. Incorrect settings may render it unusable. Always back up your configuration files before making changes. Be especially careful when modifying the repository URL, as this determines where tlmgr downloads packages.

Setting the repository to a local directory:
tlmgr conf repository file:///path/to/local/repository

Setting a proxy server:
tlmgr conf proxy http://proxy.example.com:8080/
