Initial commit

Tested fairly thoroughly on my (Arch) laptop.

I'm not sure I like systemd anymore.

At least it's better then a bunch of old shell scripts. I think that's
what they used in the dark ages (shudder)

+dis4irc-aur
+===========
+This is an *unoffical* AUR package for [Dis4IRC](https://github.com/zachbr/Dis4IRC)
+
+It creates an isolated user and includes a systemd unit file. It downloads the binary instead of compiling it (see below).
+
+It is in no way endorsed by upstream, so make sure you can distinguish between their bugs and ours ;)
+
+Also, this is my first time mirroring an AUR package to github.
+
+PRs and issues are welcome.
+
+## Why precompiled binaries
+ This package uses precompiled jar files, but does *not* have the traditional `-bin` suffix in its name.
+
+This is because the Java packaging guidelines say "You do not need to compile Java applications from source" ([See wiki](https://wiki.archlinux.org/title/Java_package_guidelines#Java_packaging_on_Arch_Linux)).
+
+This is common practice even in the official Java packages. For example `jenkins` just downloads the offical jar and checks the hash.
+
+Compiling from source would require installing gradle (or using the wrapper) and take much longer.
