+This directory show how easy it is to embed the Python interpreter in
+your own application.  The file demo.c shows you all that is needed in
+your C code.
+
+To build it, you may have to edit the Makefile:
+
+1) set blddir to the directory where you built Python, if it isn't in
+the source directory (../..)
+
+2) change the variables that together define the list of libraries
+(MODLIBS, LIBS, SYSLIBS) to link with, to match their definitions in
+$(blddir)/Modules/Makefile
