Procedure 3.
Build the package using ./autogen.sh, make, and make install and check to see that it builds successfully and that the documents are properly installed.
Create a diff file using cvs -z3 diff -u and check over the output to ensure that you have not inadvertently made changes to files you didn't intend.
Make a ChangeLog entry listing all the files changed and added.
Commit your changes: cvs -z3 commit.
Make a fresh checkout in a separate directory and repeat the build test to ensure you did not forget to cvs add anything. For this test, use make dist or make distcheck to ensure everything is being included in a buildable tarball.
