(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.

|
|
The Parma Polyhedra Library (PPL) provides numerical abstractions
|
|
especially targeted at applications in the field of analysis and
|
|
verification of complex systems. These abstractions include convex
|
|
polyhedra, defined as the intersection of a finite number of (open or
|
|
closed) halfspaces, each described by a linear inequality (strict or
|
|
non-strict) with rational coefficients; some special classes of
|
|
polyhedra shapes that offer interesting complexity/precision tradeoffs;
|
|
and grids which represent regularly spaced points that satisfy a set of
|
|
linear congruence relations. The library also supports finite
|
|
powersets and products of (any kind of) polyhedra and grids and a mixed
|
|
integer linear programming problem solver using an exact-arithmetic
|
|
version of the simplex algorithm.
