* Description

This is a MIT/GNU Scheme compatibility library for Chez Scheme. The
goal of the library is to provide those functions used in the
'Scmutils' library which are not available in Chez Scheme.

Note that the behavior of some functions differs from the one in
MIT/GNU Scheme. This is the case for example for functions
manipulating environments: MIT/GNU Scheme provides hierarchical
environments, while Chez Scheme doesn't.

* Build

To build the libraries run "make". By default it looks for a
Chez Scheme binary called "chez-scheme". If the name of your binary
is different, you can specify it as follows (for all targets):

make CHEZ=my-chez-scheme-bin

To test the build run

make test

* Install

By default "make install" will install the libraries under the prefix
"/usr/local". You can specify a different installation prefix
directory as follows:

make install PREFIX=/my-prefix/path

This will install all compiled libraries (*.so files) to
$PREFIX/lib/csvX.Y-site, where X.Y is Chez's version. If in addition
you want to install the source files, use the 'install-src' target.
They are installed in the same directory as the .so files.

* Use

Make sure that Chez Scheme can find the libraries by specifying their
location on the command line (with the appropriate flag), or by
setting the environment variable CHEZSCHEMELIBDIRS.

The library is split in the following sub-libraries:

- (mit apply-hook)
- (mit arithmetic)
- (mit arity)
- (mit core)
- (mit curry)
- (mit environment)
- (mit hash-tables)
- (mit list)
- (mit streams)
- (mit vector)

The symbol 'procedure-arity' is exported by both (mit apply-hook) and
(mit arity). The difference is that the former supports 'apply-hooks'
while the latter doesn't. Thus, if you do not use 'apply-hooks' use
the one from (mit arity), otherwise use the one from (mit apply-hook).
