(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.

|
|
Prooftree is a program for proof-tree visualization during interactive
|
|
proof development in a theorem prover. It is currently being developed
|
|
for Coq and Proof General. Prooftree helps against getting lost between
|
|
different subgoals in interactive proof development. It clearly shows
|
|
where the current subgoal comes from and thus helps in developing the
|
|
right plan for solving it.
|
|
|
|
Prooftree uses different colors for the already proven subgoals, the
|
|
current branch in the proof and the still open subgoals. Sequent texts
|
|
are not displayed in the proof tree itself, but they are shown as a
|
|
tool-tip when the mouse rests over a sequent symbol. Long proof commands
|
|
are abbreviated in the tree display, but show up in full length as
|
|
tool-tip. Both, sequents and proof commands, can be shown in the display
|
|
below the tree (on single click) or in a separate window (on double or
|
|
shift-click).
