(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.

|
|
Mercury is a logic/functional programming language which combines the
|
|
clarity and expressiveness of declarative programming with advanced
|
|
static analysis and error detection features. Its highly optimized
|
|
execution algorithm delivers efficiency far in excess of existing logic
|
|
programming systems, and close to conventional programming systems.
|
|
Mercury addresses the problems of large-scale program development,
|
|
allowing modularity, separate compilation, and numerous optimization/time
|
|
trade-offs.
