+# skyrim-cell-dump
+
+Library and binary for parsing Skyrim plugin files and extracing CELL data.
+
+The main objective of this library is to extract the form ID and X and Y coordinates of every exterior cell a plugin edits as fast as possible, ignoring the rest of the plugin.
+
+## Install
+
+```
+cargo install skyrim_cell_dump
+```
+
+Or, build yourself by checking out the repository and running:
+
+```
+cargo build --release --features build-binary
+```
+
+## Usage
+
+```
+Usage: skyrim-cell-dump.exe <plugin> [-f <format>] [-p]
+
+Extracts cell edits from a TES5 Skyrim plugin file
+
+Options:
+  -f, --format      format of the output (json or text)
+  -p, --pretty      pretty print json output
+  --help            display usage information
+```
+
+The pretty JSON format looks something like:
+
+```json
+{
+  "header": {
+    "version": 1.0,
+    "num_records_and_groups": 792,
+    "next_object_id": 221145,

+      "x": 33,
+      "y": 2,
+      "is_persistent": false
+    },
+    {
+      "form_id": 46498,
+      "editor_id": null,
+      "x": 32,
+      "y": 1,
+      "is_persistent": false
+    }
+  ]
+}
+```
+
+## Import
+
+You can include this crate in your `Cargo.toml` and get the parsed `Plugin` struct with:
+
+```rust
+use skyrim_cell_dump::parse_plugin;
+
+fn main() {
+    let plugin_contents = std::fs::read("Plugin.esp").unwrap();
+    let plugin = parse_plugin(&plugin_contents).unwrap();
+}
+```
