+# `thorin`
+`thorin` is an DWARF packaging utility for creating DWARF packages (`*.dwp` files) out of input
+DWARF objects (`*.dwo` files; or `*.o` files with `.dwo` sections), supporting both the pre-standard
+GNU extension format for DWARF packages and the standardized format introduced in DWARF 5.
+
+`thorin` was written as part of the implementation of Split DWARF in `rustc`. A Rust implementation
+of a DWARF packaging utility is easier to integrate into the compiler and can support features like
+loading dwarf objects from archive files (or rustc's rlibs) which are helpful in supporting
+cross-crate Split DWARF packaging in `rustc`.
+
+## Usage
+To use `thorin` in your own project, add it to your `Cargo.toml`:
+
+```toml
+thorin-dwp = "0.3.0"
+```
+
+See the [`thorin-bin`](../thorin-bin/README.md) crate for an example of using `thorin`'s library
+interface.
+
+## Stability
+`thorin`'s library interface is intended for use by `rustc` for its *Split DWARF* support, it
+currently comes with no stability guarantees and may change at any time.

+#### Name
+<sup>
+<code>thorin</code> is named after <i>Thorin Oakenshield</i> from <i>The Hobbit</i>, as Thorin is
+a dwarf who leads other dwarves. <code>thorin</code> uses the <code>gimli</code> library
+(named after a dwarf from <i>Lord of the Rings</i>) to read <i>DWARF</i> format debug information,
+the name of which is a medieval fantasy complement to <i>ELF</i>, the file format for executables
+and object files.
