+
+(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

+
+(3) --enable-ENCODING
 
-(1) --enable-configuration=CONFIGURATION
+  In addition to (2), you can enable other optional and switchable character
+  encodings.
 
-You can choose the functionality with this option. Please select in the
-following candidates.
+    $ ./configure --enable-default-encoding=eucjp --enable-eucjp --enable-sjis
 
-  - 'full': compiled with full spec including all supported SRFIs.
-  - 'r5rs': compiled with the functionality only defined in R5RS.
-  - 'siod': compiled in compatible with SIOD(Scheme In One Defun).
 
-(2) --enable-multibyte=ENCODING
+Then type 'make' at the top directory.
 
-By default, SigScheme is built with UTF-8 as default encoding. You can change
