+# Wuffs Mirror (release/c)
+
+This repository mirrors a subset of the
+[Wuffs](https://github.com/google/wuffs) (Wrangling Untrusted File Formats
+Safely) repository.
+
+Wuffs is both a programming language (Wuffs-the-language) and a standard
+library (Wuffs-the-library) written in that language. The Wuffs toolchain
+converts from Wuffs-the-language to C and Wuffs-the-library is available as a
+single C file - a [header file
+library](https://github.com/nothings/stb/blob/master/docs/stb_howto.txt).
+
+People who just want to *use* Wuffs-the-library in its C form (instead of
+*modifying* its Wuffs form or otherwise needing Wuffs-the-language tools) only
+need that one C file.
+
+This repository's [`release/c`](./release/c) directory contains that C file (at
+various versions). It mirrors the `release/c` directory of the [original Wuffs
+repository](https://github.com/google/wuffs) (except for the "unsupported
+snapshot" version). By excluding everything else, this repository is much
+smaller and changes much less frequently.
+
+
+## Updates
+
+This repository's `release/c` directory is manually updated by the
+`script/sync.sh` shell script, which also logs to [`sync.txt`](./sync.txt).
+
+
+## Disclaimer

+This is not an official Google product, it is just code that happens to be
