+/* Steps to create a new object:
+
+ 1. Declare the struct for your object in a header file somewhere.
+ Remember that it must begin with
+
+ struct lcrecord_header header;
+
+ 2. Put a DECLARE_LRECORD() for the object below the struct definition,
+ along with the standard XFOO/XSETFOO junk.
+
+ 3. Add this header file to inline.c.
+
+ 4. Create the methods for your object. Note that technically you don't
+ need any, but you will almost always want at least a mark method.
+
+ 5. Define your object with DEFINE_LRECORD_IMPLEMENTATION() or some
+ variant.
+
+ 6. Include the header file in the .c file where you defined the object.
+
+ 7. Put a call to INIT_LRECORD_IMPLEMENTATION() for the object in the
+ .c file's syms_of_foo() function.
+
+ 8. Add a type enum for the object to enum lrecord_type, earlier in this
+ file.
