+C-API Specs
+
+These specs test the C-API from Ruby. The following are conventions for the
+specs:
+
+1. Put specs for functions related to a Ruby class in a file named according
+ to the class. For example, for rb_ary_new function, put the specs in
+ optional/capi/array_spec.rb
+2. Put the C file containing the C functions for array_spec.rb in
+ optional/capi/ext/array_spec.c
+3. Name the C extension class 'CApiArraySpecs'.
+4. Name the C functions 'array_spec_rb_ary_new'.
+5. Attach the C function to the class using the name 'rb_ary_new'
