+  "TOML parsing, manipulation, and pretty-printing library (1.0.0-compliant)"
+description: """\
+OTOML is a library for parsing, manipulating, and pretty-printing TOML files.
+
+* Fully 1.0.0-compliant.
+* No extra dependencies: default implementation uses native numbers and represents dates as strings.
+* Provides a functor for building alternative implementations: plug your own bignum and calendar libraries if required.
+* Informative parse error reporting.
+* Pretty-printer offers flexible indentation options."""
