+# To build pforth:
+#
+#    cmake .
+#    make
+#
+# That will create the following files:
+#    fth/pforth   # executable that loads pforth.dic
+#    fth/pforth.dic
+#    fth/pforth_standalone # executable that does not need a .dic file
+#
+# The build has several steps
+# 1. Build pforth executable
+# 2. Build pforth.dic by compiling system.fth
+# 3. Create a pfdicdat.h header containing a precompiled dictionary
+#    as C source code.
+# 4.  Build pforth_standalone using the precompiled dictionary.
