-While I was reading the [R7RS
-specification](https://standards.scheme.org/official/r7rs.pdf), I was a little
-annoyed by how broken up the standard library seemed to be.  While the most
-egregious example is maybe `(scheme case-lambda)`, which exports ...  only
-`case-lambda`, the other libraries like `(scheme write)` for `display`, `(scheme
-cxr)` for functions like `caddr` but not `cddr`, and the rest didn't really seem
-logical to me.  Plus, in CHICKEN scheme, the one I usually use, `utf8` is an egg
-you need to install separately...

 To ameliorate these minor warts in what I otherwise consider to be an excellent
 language, `chicanery` was born.  It's kind of like a prelude, I suppose?  It
 imports all `r7rs` modules and re-exports their identifiers, and makes sure the
-implementation is Unicode-aware.  It also includes a few extras ;)

 ## Chicanery extras
 
-I also thought it was strange that `map`, `for-each`, and `append` apply to
-lists only, while `vector-map` and `string-for-each`, exist, for example.
-`chicanery` prefixes the default `map`, `for-each`, and `append` functions with
-`list-`, and redefines those identifiers to functions that are generic over
-Scheme's base collection types (lists, strings, vectors, bytevectors where
-applicable).  I didn't make the functions fully-generic to keep them efficient
-and because I don't know how to do that, but you can still use `vector-append`
-or `list-map` if you know what type you need and want speed.
+The following are included in the chicanery library because I like them.
 
-In a similar vein, I've also added generic functions `ref` and `copy` that
-dispatch to `string-ref`, `list-copy`, and the like.

-Other extras include
-
-- `(atom?  x)` determines whether `x` is an atom (i.e., not a pair or null)
-- `(read-port)`, `(read-port port)` reads a port until hitting end-of-file (IDK
-  why this isn't in R7RS!), in chunks of `read-port-chunk-size`
-- `(defined?  x)` returns whether the symbol `x` is bound to a variable
+- `(atom? x)` determines whether `x` is an atom (i.e., not a pair or null)
+- `(slurp [port])` reads a port until hitting end-of-file (IDK
+  why this isn't in R7RS!)
 - `(with-input-from-string str thunk)` calls `thunk` with `str` bound as the current-input-port.
 - `(with-output-to-string thunk)` calls `thunk` and returns a string of the output.
 - `(displayed x)`, `(->string x)` returns `x` as a string (via `display`)
 - `(written x)` returns `x` as a string (via `write`)
-- `(print x ...)` displays `x ...` followed by a newline
+- `(print . xs)` displays `xs` followed by a newline
 
 ## Todo
 
-- Support multiple scheme implementations.  I tried doing this (see the [multiple-impls](https://git.acdw.net/chicanery/?h=multiple-impls) branch), but it kept not working in weird ways, plus it was like whack-a-mole with all the different schemes and just exhausting.
