What's SigScheme
----------------
SigScheme is a R5RS Scheme interpreter for embedded use.
Homepage:
http://code.google.com/p/sigscheme/
Git repository:
git clone https://github.com/uim/sigscheme.git
See following files for further information.
- doc/spec.txt: specifications of SigScheme
- QALog: quality assurance state
Please report us if you find a problem. And if you have a time, run
'make-report.sh' and send us the result regardless of PASSed or FAILed. It
greatly helps the development, especially for non-PC platforms.

How to build
------------
GNU make is requied to build.
Run ./configure with some options at the top directory.
$ ./configure [--enable-conf=CONF] [--enable-default-encoding=ENCODING]
(1) --enable-conf=CONF
This specifies a base configuration set. Select one from the list below
suitable for your purpose.
- full: compile with full features but broken ones
- regular: (default) compile with typically needed features
- small: compile with primary features only
- r5rs: compile with strict R5RS conformances
- siod: emulate some SIOD features and bugs
- dev: developer-friendly configuration
- uim: configure for uim
(2) --enable-default-encoding=ENCODING
SigScheme normally selects UTF-8 as default encoding. You can change it by
this option as follows.
$ ./configure --enable-default-encoding=eucjp
Following encodings can be specified.
- utf8
- euccn
- eucjp
- euckr
- sjis
(3) --enable-ENCODING
In addition to (2), you can enable other optional and switchable character
encodings.
$ ./configure --enable-default-encoding=eucjp --enable-eucjp --enable-sjis
Then type 'make' at the top directory.
$ make
Test
----
$ make check
Installation
------------
$ make install
How to use
----------
To run SigScheme in interactive mode, type as follows.
$ sscm
To execute a Scheme script, specify it as argument.
$ sscm <filename>
