* Add package for nginx@1.12.0
Includes support for:
- zlib
- pcre (and pcre-jit)
- openssl (https support)
Built and basics tested on CentOS 7. I haven't tested the `https`
support [yet].
* Include final bit of doc string sentence.
I trimmed the docstring that I lifed from https://nginx.org/en a bit
too aggressively and left a '...' to remind me to fix it.
Apparently I need more obvious reminders.
Thanks @davydden!
