+# SKINT Precursors
+                         
+This directory contains original Scheme code for autogenerated parts od SKINT C source. 
+To re-generate these files, one has to have working version of SKINT interpreter and [SFC compiler](https://github.com/false-schemers/sharpF). 
+Generation is performed with the help of Skint scripts located in the `/pre` subdirectory. Assuming that both `skint` and `sfc` binaries are just above
+the skint directory tree, the following commands will do the trick:
+
+```
+$ ./skint skint/pre/nsf2h.ssc skint/pre/n.sf skint/n.h
+$ ./skint skint/pre/nsf2c.ssc skint/pre/n.sf skint/n.c
+$ ./skint skint/pre/scm2c.ssc skint/pre/s.scm skint/s.c
+$ ./skint skint/pre/scm2c.ssc skint/pre/t.scm skint/t.c
+$ ./skint skint/pre/ksf2c.ssc ./sfc skint/pre/k.sf skint/k.c
+```
+
+Please note that this step is optional, but may be needed to make enhancements and fix bugs in the
+autogenerated C code.
