+# depctrl feed maker
+
+Makes [DependencyControl](https://github.com/TypesettingTools/DependencyControl) update feeds for [Aegisub](https://tilde.club/~garret/fansub.html#recommended-aegisub-builds) automations, so you don't have to write all that JSON by hand.
+
+![xkcd 1319](https://imgs.xkcd.com/comics/automation.png)
+
+## Requirements
+
+you'll need Lua 5.1, LuaJSON, LuaFileSystem, `argparse`, Moonscript, and `sha1`.
+Currently you'll also need `inspect`, because I use it for debugging, and haven't bothered to get rid of the `require` yet.
+
+Ubuntu install commands:
+```
+sudo apt install lua5.1 lua-json lua-filesystem lua-argparse lua-inspect luarocks
+sudo luarocks install sha1 moonscript
+```
+I think that might install LuaFileSystem twice. Not entirely sure, pls boop if you have better commands.
+
+## Usage
+
+Configuration is done via a Lua script. An example config is maintained in `conf.lua`.
+
+To make a feed, run:
+
+```
+make-feed.lua --macros /path/to/your/macros/ --modules /path/to/your/modules/ --config /path/to/your/conf.lua --output /path/to/DependencyControl.json
+```
+
+You can omit `--macros` or `--modules` if you don't have any. You can omit both, but then you just get a feed with no scripts.
+
+You can also omit `--output`, and the feed will output to `DependencyControl.json`. If you want to output to stdout, use `--output /dev/stdout`.
+
+You may not omit `--config`. If you want to read it from stdin, use `--config /dev/stdin`.
+
+`--output` and `--config` can be abbreviated to `-o` and `-c` respectively.
+
+## A word on security
+
+no.
+
+Yes, this executes arbitrary code. No effort is made to prevent scripts from doing bad things.
+This shouldn't be a problem, however, because it's _your_ arbitrary code. _You_ wrote it, so you should know if it does bad things.
+
+If you make scripts that do bad things, run them, and bad things happen, the only person you have to blame is yourself.
