+Notes for Scheme-to-C port for FreeBSD:
+
+The documentation provided on the X library interface for Scheme-to-C
+was very limited and as a result I'm not sure if I've got it right.
+Instead of using having the compiler link the library archives libsc.a
+(the standard schemetoc library) or scxl.a (the x library), two shared
+libraries are included, libsc.so.1.0 and libscxl.so.1.0.  
+
+The syntax of the scc compiler has been extended to automatically
+use dynamic linking unless the -static flag is specified on the scc
+command line.
+
+Those not wishing to use the X library support can delete the following
+files:  
+
+libscxl.so.1.0 		The shared lib.
+schemetoc/scxl.a	The library archive.
+bin/scixl		The X lib interpreter.
+
+Each is about 1.4 megabytes.
