+# Read #define's from stdin and translate to Python code on stdout.
+# Very primitive: non-#define's are ignored, no check for valid Python
+# syntax is made -- you will have to edit the output in most cases.

+# XXX To do:
+# - accept filename arguments
+# - turn trailing C comments into Python comments
+# - turn C string quotes into Python comments
+# - turn C Boolean operators "&& || !" into Python "and or not"
+# - what to do about #if(def)?
+# - what to do about macros with parameters?
+# - reject definitions with semicolons in them
