(My OCD kicked in today...) Remove repeated package names, capitalize first word, remove trailing periods and move overlong descriptions to longDescription. I also simplified some descriptions as well, when they were particularly long or technical, often based on Arch Linux' package descriptions. I've tried to stay away from generated expressions (and I think I succeeded). Some specifics worth mentioning: * cron, has "Vixie Cron" in its description. The "Vixie" part is not mentioned anywhere else. I kept it in a parenthesis at the end of the description. * ctags description started with "Exuberant Ctags ...", and the "exuberant" part is not mentioned elsewhere. Kept it in a parenthesis at the end of description. * nix has the description "The Nix Deployment System". Since that doesn't really say much what it is/does (especially after removing the package name!), I changed that to "Powerful package manager that makes package management reliable and reproducible" (borrowed from nixos.org). * Tons of "GNU Foo, Foo is a [the important bits]" descriptions is changed to just [the important bits]. If the package name doesn't contain GNU I don't think it's needed to say it in the description either.

|
|
hwloc provides a portable abstraction (across OS,
|
|
versions, architectures, ...) of the hierarchical topology of
|
|
modern architectures, including NUMA memory nodes, sockets,
|
|
shared caches, cores and simultaneous multithreading. It also
|
|
gathers various attributes such as cache and memory
|
|
information. It primarily aims at helping high-performance
|
|
computing applications with gathering information about the
|
|
hardware so as to exploit it accordingly and efficiently.
|
|
|
|
hwloc may display the topology in multiple convenient
|
|
formats. It also offers a powerful programming interface to
|
|
gather information about the hardware, bind processes, and much
|
|
more.
