proconfig is a Linux kernel patch which lists the running kernel's compilation options in /proc/config. This makes kernel image administration easy if you compile a lot of kernels or admin a lot of machines. The code is compiled as a kernel module by default. The patch integrates with the kernel Makefiles, so it shows up conveniently under make menuconfig and friends.

proghelp generates a Web application using a modified create table SQL syntax. It generates PosgreSQL stored procedures, a db layer, a BLL layer, a Web interface using WebToolkit (Wt), and random data for testing. It sets up default security: authentication and authorization. Modified SQL grammar allows you to mark search keys: the project automatically generates function calls and stored procedures with these search keys and exposes them in the UI. The project looks at foreign key references and automatically builds select dialog boxes.
