This library is based on the CK-macro system described in
"[Applicative syntax-rules: macros that compose better](http://okmij.org/ftp/Scheme/macros.html#ck-macros)"
by Oleg Kiselyov.
This library provides the core `ck` macro,
many useful (and some not-so-useful) portable CK-macros,
the `ck-wrapper` procedure, and many wrappers of R5RS procedures.

This library is the source for the
[ck-macros egg for CHICKEN Scheme](http://wiki.call-cc.org/eggref/5/ck-macros),
but everything in
[portable.scm](https://gitlab.com/jcroisant/ck-macros/blob/master/lib/portable.scm)
should work on any Scheme implementation of R5RS or later], and
[ck-wrapper.scm](https://gitlab.com/jcroisant/ck-macros/blob/master/lib/ck-wrapper.scm)
and [wrappers-r5rs.scm](https://gitlab.com/jcroisant/ck-macros/blob/master/lib/wrappers-r5rs.scm)
should work on any Scheme that provides `er-macro-transformer`.

If you create a useful or interesting general-purpose CK-macro,
or an improvement to an existing CK-macro,
please contact the maintainer (John) so your contribution can be added to the library.
