(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.

'' GMP is a free library for arbitrary precision arithmetic, operating
|
|
on signed integers, rational numbers, and floating point numbers.
|
|
There is no practical limit to the precision except the ones implied
|
|
by the available memory in the machine GMP runs on. GMP has a rich
|
|
set of functions, and the functions have a regular interface.
|
|
|
|
The main target applications for GMP are cryptography applications
|
|
and research, Internet security applications, algebra systems,
|
|
computational algebra research, etc.
|
|
|
|
GMP is carefully designed to be as fast as possible, both for small
|
|
operands and for huge operands. The speed is achieved by using
|
|
fullwords as the basic arithmetic type, by using fast algorithms,
|
|
with highly optimised assembly code for the most common inner loops
|
|
for a lot of CPUs, and by a general emphasis on speed.
|
|
|
|
GMP is faster than any other bignum library. The advantage for GMP
|
|
increases with the operand sizes for many operations, since GMP uses
|
|
asymptotically faster algorithms.
