+# dsort
+
+bevy/egui desktop app for performing version-based line sorting, and blank-line cleanup of line-delimited data.
+
+![dsort screenshot](demo.gif "dsort")
+
+this is designed and built specifically for one single person, to help make their life simpler - this is not general-purpose, or one-size-fits-all.
+
+## installation
+
+check out the [releases](https://git.thermokar.st/thermokarst/dsort/releases) page for pre-built binaries.
+
+## development
+
+```bash
+cargo run
+```
+
+## release process
+
+ensure the following are available on the system
+- `mingw` toolchain (`brew install mingw-w64`)
+- `rust` (whatever `rustup` gave me)
+
+```bash
+# et voila
+./package.sh
+```
