ROOT is part of Debian Lenny 1 and was maintained by Christian Holm Christensen. During the last freezing cycle leading to the current Debian stable version (Squeeze), ROOT was removed from testing and subsequently removed from unstable aswell. There has been no explanation as to why ROOT did not make it to Squeeze 2. There may be license issues, or lack of time to maintain. Whatever the reason, there is a strong need to have debs available in a repository, that are compliant with current Debian stable.
The arduous effort to make Debian packages of ROOT available in a repository stems from the need to install ROOT in various computers used by students and faculty. The large size of ROOT makes it unsuitable for repetitive plain compilation of the source code.
The following Debian repository for ROOT with the latest Pro release (5.32/00) is meant to be as Debian 6.0 (Squeeze) compliant as possible. In particular, the update from v5.18/00 in Debian 5.0 (Lenny) should be unbreakable.
