The current version seems to accelerate AES and SHA families.
Size increase on x86_64 is <10k in our case.
It can make quite some performance difference; I tried
$ time ./result-dev/bin/nettle-hash -a sha256 /some/file/around/2G
And the total CPU time went down from 8.5s to 2s (single thread).
Now it matches the time of openssl
$ time openssl sha256 /some/file/around/2G
Of course, in real life it will be much harder to notice a difference...
Platforms without support for this (e.g. i686) seem to still build fine,
and ARMv7 cross-build also succeeds for me, so hopefully all is OK.
He prefers to contribute to his own nixpkgs fork triton.
Since he is still marked as maintainer in many packages
this leaves the wrong impression he still maintains those.
(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.
