Rolobook is a web-based workgroup address book / calandar application. This is a fairly involved CGIPAL demo that you can use or embellish as you like.

Also includes

scriptpal executes cgipal-style scripts in a batch fashion from the command line, writing the result to standard output. Useful for many template-processing and report generation tasks.
version 0.91B
PocketSQL is a compact multiuser database that can be embedded in applications. It uses a subset of the SQL command language. PocketSQL features reasonable SQL functionality and it can connect easily with the shell, external programs, and files. It is small enough to link directly into programs rather than using a client-server approach (thus, pocketSQL must be invoked on the same file system that the data resides on, rather than across a network). Limitations include lack of indexing and constraints on compound logic in where-clauses. This distribution includes a command line interface and simple C language API. For a web-based interface, download cgipal (above) instead. Current version is for Unix-like platforms.
