Guile-reader is a reader creation framework for Guile.  It can be
thought of as an alternative to Guile's built-in reader.  The purpose of
guile-reader is to allow to easily create readers for different variants
of the Scheme/Lisp syntax.  Its design allows to re-use and assemble
various parts of a parser called "token readers".  It comes with a
library of re-usable token readers that can be used to build a Scheme
reader with various extensions.

Additionally, guile-reader aims to improve on Guile's reader sub-system
by allowing for the coexistence of several, potentially incompatible,
readers within a single Guile program.  In particular, it provides a
``confinement'' mechanism that confines changes made via `read-set!' and
`read-hash-extend' to the calling module.

Excerpt from the `NEWS' file:

  * Modified `make-reader' with support for source position recording.

  * New token readers such as: SRFI-30 block comments, SRFI-62 S-exp
    comments, R6RS-like square bracket S-exps, curly-brace S-exps.

  * New high-level API (namely `make-alternate-guile-reader') to create
    Scheme readers.

  * Read extension confinement module: replaces `read-options-interface'
    and `read-hash-extend' with confined variants.

  * Online documentation of token readers and improved documentation.

  * Bug fixes.

Thanks,
Ludovic.
