The codex tool is a simple program that examines an OpenOffice.org document, looking for code listings and snippets. It extracts the body of each listing and snippet to separate text files.
A snippet is one or more adjacent paragraphs that have a
code style applied, such as Preformatted Text.
A listing is like a snippet, but it starts with a caption
style, followed immediately by code style paragraphs.
You can control which style names codex considers to be
caption styles and which are code styles by means of a configuration
file. The default configuration file uses Caption as the
name of the sole caption style and Code and Preformatted
Text as the names of the two code styles.

Read the man pages online:
codex.1 (man page for the program)
codex.5 (man page for the configuration file format)
The source code includes a standard configure script.
It checks for a few dependencies, in particular two libraries:
libxml2, which most Linux distributions include
libzip, which is less widely distributed, but easily obtained nonetheless
It also checks for the strcasecmp function, which is
part of the GNU C library, but might not be available on other
platforms.
