Coccinelle (http://coccinelle.lip6.fr/) is a program which performs mechanical transformations on C programs using semantic patches. These semantic patches can be used to implement automatic refactoring and maintenance tasks. Add a set of basic semantic patches to convert common patterns related to the struct object_id transformation, as well as a README.
