PBone RPM Search is a specialized tool for users of the Linux
operating system — especially for users of the Red Hat Linux
distribution. PBone RPM Search finds the names of rpm packages that
contains filenames given by user. It also supports “provides” rpm
tag. The system is especially helpful for these users who install
or compile new software but for some reasons haven’t installed all
of the required librares or files and are not able to investigate
what rpm packet is missing on their system.
